Background

The cash refers to money which can be paid at any time by a unit, and comprises stock cash, bank deposits, other money funds, a zero-balance account money amount, a financial return amount, money paid by a financial direct payment mode and the like.

Cash flow is a general term of cash inflow, cash outflow and total amount of cash generated by certain economic activities (including business activities, investment activities, financing activities and non-recurring items) according to cash receipt and payment implementation of enterprises during certain accounting period.

The cash flow is the amount of inflow and outflow of cash and cash equivalents of an enterprise in a certain period, is a parameter which can reflect the essence of the enterprise, and plays a very important role for the enterprise.

Aiming at the actual business of a financial user, when the voucher is manually input, the input of a cash subject is related, and financial staff is required to manually fill cash flow according to the actually occurring business information and a related system. However, this method is not only labor intensive but also prone to input errors, and accuracy is difficult to guarantee.

In addition, because the labeling of cash flow is the entry level for cash subjects, the labeling is performed according to actual business activities. The large batch of automatic certificates generated by the business documents cannot be marked, and the manual marking can be carried out only after the certificates are generated and opened again by financial staff.

Detailed Description

Embodiments and examples of the present invention will be described in detail below with reference to the accompanying drawings.

The scope of applicability of the present invention will become apparent from the detailed description given hereinafter. It should be understood, however, that the detailed description and the specific examples, while indicating preferred embodiments of the invention, are given by way of illustration only.

Cash flow is divided into two directions, cash out and cash in. Cash-out is the total capital expenditure for an investment project, including fixed asset investment, liquidity investment, operating costs, and the like. A cash inflow is the total monetary revenue that occurs for an investment project, including revenue of business, residual or variable income, reclaimed liquidity, etc.

The accounting subjects can be classified into general subjects, cash subjects, bank subjects, receivable subjects, payable subjects, and the like according to their subject attributes. The cash item and the bank item are collectively referred to as a cash item, and the items having other attributes are referred to as counter items of the cash item. In the following, "counter subjects of cash subjects" and "counter subjects" are used interchangeably.

According to the actual business of a specific application such as an enterprise, cash flow items used during enterprise cash flow labeling can be collected in advance, and then the cash flow items are recorded in a book and are arranged to form an EXCEL or text file. On the basis, the mapping relation between the counter-subject and the cash flow item can be configured and stored in the database. And a mapping relation database of the other subjects and the cash flow items can be formed in a text filling or EXCEL importing mode. Multiple counterparty accounts may correspond to the same cash flow item, but each counterparty account corresponds to only one pair of cash flow items. Each pair of cash flow items includes a cash flow inflow item and a cash flow outflow item. The mapping relation between the other subject and the cash flow item generally only needs to be initialized once, and according to the system version management, the mapping relation of the previous year can be selectively copied and inherited in the next year.

Fig. 1 shows a flowchart of a preferred embodiment of the automatic document labeling method according to the present invention.

At step S100, upon entry of the voucher entry, an entry of a cash subject is received, including the direction and amount of the cash subject, after which the entered voucher is saved, which has unique primary key information such as id within the system. Because the method of the invention realizes the automatic marking of the cash flow item, the manual recording/marking of the small box maintained by the cash flow item is not required to be popped up when the voucher entry is recorded. If the credential is successfully saved, processing proceeds to step S200; otherwise, the process of the voucher entry is finished, and the entry of the next voucher is waited.

In step S200, the primary key information of the voucher, such as id, is obtained for use in subsequently saving the automatic labeling result of the cash flow item.

In step S300, the flow direction of the net cash flow of the voucher is determined according to the direction and/or amount of the cash item entry in the voucher entry, so as to determine the cash flow project direction that the voucher needs to be automatically labeled.

In an embodiment, the step S300 of determining the voucher net cash flow inflow and outflow direction comprises the following sub-steps, as shown in fig. 2.

In step S301, it is determined whether the directions of lending in the entries where the cash subjects of the entire voucher are respectively located are all the same. If so, the process proceeds to step S310; otherwise, the process proceeds to step S320.

In step S310, it is determined whether all the loan directions of the entries in which the cash subjects of the entire voucher are located are loan directions. If so, the process proceeds to step S311; otherwise, if all are credits, the process proceeds to step S312.

In step S311, the voucher net cash flow direction is determined as inflow.

In step S312, the voucher net cash flow direction is determined to be out.

In step S320, when the entire voucher includes more than two cash subjects and the directions of lending of the respective entries are not completely consistent, the cash subjects with equal amounts and opposite directions are subtracted.

In step S321, it is determined whether the loan directions of the entries in which the remaining cash subjects after the deduction are respectively located are all the same. If so, the process proceeds to step S330; otherwise, the process proceeds to step S340.

In step S330, it is determined whether all of the loan directions of the entries in which the remaining cash subjects after the deduction are located are loans. If so, the process proceeds to step S331; otherwise, if all are credits, the process proceeds to step S332.

In step S331, the voucher net cash flow direction is determined as inflow.

At step S332, the voucher net cash flow direction is determined to be out.

In step S340, when the remaining cash items include more than two cash items and the borrowing and lending directions of the entries in which the two cash items are respectively located are not completely consistent, it is determined whether the remaining cash items have consistent entry amount symbols. If so, the process proceeds to step S350; otherwise, the process proceeds to step S360.

In step S350, when the remaining cash item entry amounts match in sign, for example, all of the credit amounts are positive or all of the credit amounts are negative, and the credit amounts are combined, that is, subtracted.

At step S351, it is determined whether the debit balance is greater than 0. If so, the process proceeds to step S352; otherwise, the process proceeds to step S353.

In step S352, the voucher net cash flow direction is determined as incoming.

At step S353, the voucher net cash flow direction is determined to be out-flow.

In step S360, when the remaining cash subject entry amount symbols do not completely match, the difference between the debit cash subject amount and the credit cash subject amount is calculated.

In step S361, it is determined whether the difference between the debit cash subject amount and the credit cash subject amount is greater than 0. If so, the process proceeds to step S362; otherwise, the process proceeds to step S363.

In step S362, the voucher net cash flow direction is determined as incoming.

At step S363, the voucher net cash flow direction is determined to be out-flow.

In an embodiment, the steps S311, S331, S352, and S362 having the same function may be combined into one step. Also, the above steps S312, S333, S353, S363 having the same function may be combined into one step.

In step S400, the net cash flow amount of the voucher is determined based on the amount of the voucher' S cash item entry. The voucher net cash flow amount is the sum of the directions of the debits from the cash subject entries of the voucher. That is, the net cash flow amount of the voucher is calculated as follows:

the total cash flow amount of the voucher amt-cash subject debit amount-cash subject credit amount

For example, when a company pays 500 yuan for electricity by cash and manually inputs a certificate, the loan entry is as follows:

wherein, the subject '51010401 unit management fee-other fee-electric fee' is the subject of the other party; the subject '100101 cash in stock-renminbi' is a cash subject, the direction of the amount of the entry is credit, the net cash flow amount of the voucher amt is calculated to be 0-500 according to the above calculation formula, and then the net cash flow amount of the voucher is determined to be 500 yuan. In step S300, the direction of the net cash flow for the voucher is confirmed as out since all of the directions of the debits and credits of the cash subjects of the voucher are credits.

At step S500, it is determined whether the voucher net cash flow amount is greater than 0. If the voucher net cash flow amount is greater than 0, the process proceeds to step S600; otherwise, if the net cash flow amount of the voucher is equal to 0, although the entry has the cash subjects and the other subject voucher, the voucher is not marked with the cash flow item, because the voucher has no influence on the cash flow, and the processing is finished.

In step S600, invalid ones of the counter subjects of the cash subjects of the voucher are removed to reduce the number of annotations for the cash flow item.

In an embodiment, the step S600 of removing the invalid counterpart subject includes the following sub-steps, as shown in fig. 3.

In step S601, it is determined whether the loop of each line entry of the loop detection voucher ends. If so, the process proceeds to step S605; otherwise, the process proceeds to step S602.

In step S602, the debit and credit directions and the amount of money in a pair of party subject entries of the voucher are recorded.

In step S603, the recorded loan direction and amount of the other subject entry are saved as an array and temporarily stored in the memory. The process then proceeds to step S601, and the directions and amounts of the loan in the records of the other party 'S subjects are recorded and saved until the directions and amounts of the loan in the records of all the other party' S subjects are recorded.

In step S605, the temporary storage array in the memory is read.

In step S606, it is determined whether there is a pair of entries having equal entry amounts but opposite directions. If so, the process proceeds to step S607; otherwise, the process proceeds to step S608.

In step S607, the counterpart subject entry having the same entry amount but the opposite direction is removed from the array.

In step S608, it is determined whether there is a pair of entries with the same entry debit direction but with the sum of the amounts equal to zero. If so, the process proceeds to step S609; otherwise, no processing is performed on the array.

In step S609, the other subject entry with the same loan direction but with the sum of the amounts equal to zero is removed from the array, and the remaining other subjects in the array can be automatically labeled later.

In step S700, cash flow items corresponding to each of the remaining counter subjects in the array and having the same direction as the net cash flow direction of the voucher are determined based on the remaining counter subjects in the array and the pre-established mapping relationship configuration between the counter subjects and the cash flow items based on the cash subjects. For example, if the voucher net cash flow direction is incoming, the corresponding incoming cash flow item is taken.

For example, also using the voucher example in step S400, when a certain enterprise pays 500 yuan for electricity using cash and manually enters the voucher, the loan entry is as follows:

according to the mapping configuration between the other party subject of the cash subject and the cash flow rate item, which is established in advance, the mapping relationship between the other party subject '51010401 unit management fee-other fee-electric fee' and the cash flow rate item is assumed as follows:

for this credential example, the credential net cash traffic direction has been determined to be egress, as described above. Thus, the cash flow item takes as the basis for the annotation the outflow item, namely "204 pays additional cash related to daily activities".

In other embodiments, step S600 may also be omitted. In this case, step S700 is performed based on the other subject of the voucher.

In step S800, the amount of the determined cash flow item is marked as an amount in the opposite direction to the corresponding counterpart subject loan amount. For example, in the above voucher example, the cash flow item is marked with the amount in the opposite direction of the debit amount 500, which is the amount of "51010401 unit management fee-other fee-electric fee", which is the corresponding party subject, as the determined cash flow item, which is "204 paid cash related to daily activities", that is, the marking result is as follows:

in step S900, the cash flow item tagging result is stored in association with the primary key information, such as id, of the corresponding voucher for subsequent viewing, modification, and the like. The user can check the labeling condition of the cash flow item, modify the cash flow item and the amount, add or delete rows, recover the default labeling result and the like by manually clicking. An example of the cash flow item annotation result is shown in FIG. 4.

In an embodiment, the method of the present invention may also provide a batch annotation function to check the correctness of the annotation of cash flow items during accounting, such as at the end of the month. Because the voucher storage and the cash flow item labeling are two separate steps, after the voucher storage is successful, the automatic labeling of the voucher may not be successfully completed due to equipment or network faults and the like, so that the voucher is not labeled. By providing the batch marking function, the cash flow item marking list of the certificate entry in the specified period can be checked and viewed/displayed, for example, the certificate number, the other part subject entry in the certificate, the amount, the cash flow item and the like are displayed, and screening is carried out according to marked or unmarked conditions. And marking the unmarked voucher entries one by one according to the processing of the steps S200 to S900 under the condition that the user selects batch marking.

In an embodiment, when the mapping relationship between the counterpart item of the cash item and the cash flow volume item is configured in advance, the inflow/outflow direction of at least one counterpart item may be set. In this case, the method of the present invention further comprises, after step S200, determining whether the mapping configuration has set at least one pair of inflow and outflow directions for the objective. And for the opposite subjects with no or bidirectional inflow and outflow directions, determining the cash flow net cash flow inflow and outflow directions corresponding to the cash flow item directions marked by the entries according to the step S300. For the opposite subject whose inflow and outflow direction has been set to inflow or outflow only, step S300 is not executed any more, but the direction of the cash flow item of the entry label corresponding to the corresponding opposite subject is determined according to the inflow and outflow direction setting of the opposite subject. For the other subject set as only inflow, the cash flow item direction of the corresponding entry label is inflow. Similarly, for the counterpart subject set to only flow out, the cash flow item direction of its corresponding entry label is flow out.
