Before posting a document, the accountant should compare its date with the supporting document and check the selected period and the sequence of related transactions. What a day in 1C means The query “day in 1C” may refer to the document date, the program’s working date, the boundaries of the reporting period or the date by which an entry is included in a report. These are different parameters, so it is first necessary to determine exactly where the question arose: when creating or posting a document, generating a report or exchanging data. The document date indicates the point in time to which the entry in the information database relates. However, the date field alone is not sufficient to assess whether the accounting treatment is correct. The substance of the transaction, the source document, the posting status and the register entries are also relevant. If the user changed the date but did not repost the document, the final data in reports may remain unchanged or be included in a period other than the expected one. The working date is used to complete new documents, but the date of a business transaction is supported by accounting documents. For tax accounting purposes, the accountant compares the information in 1C with accounting documentation, source documents, invoices, tax registers and other documents used to determine taxable items and tax liabilities (Article 202 of the Tax Code of the RK). What the accountant should check If a document was assigned to the wrong day or does not appear in the required report, it is recommended to check the following in sequence: - the document date and time; - the date of the source document or other supporting document; - the organisation, department and responsible user; - the transaction type and completed details; - whether the document has been posted; - the period specified in the report; - filters and other report parameters; - the sequence of related documents; - the result of data exchange with another information database or external service; - the version of the configuration being used and the installed fixes. Particular attention should be paid to documents created on the basis of other documents. Changing the date of one link may affect the sequence in which the entire transaction is recorded. After making a correction, it is necessary to check not only the document itself but also the related entries, registers and final report. If the period is closed, the date should be changed only after assessing the consequences. The correction may affect reports, calculations and reconciliations that have already been prepared. Before making the correction, the original information should be recorded, the cause of the error determined and the procedure established by the organisation for correcting accounting data applied. The taxpayer independently organises tax accounting and determines the forms used to summarise information in tax registers in compliance with the requirements of the Tax Code of the RK (Article 202 of the Tax Code of the RK). What to do in the event of a date error First, reproduce the issue using the specific document and record its type, date, number and expected result. Then compare the supporting document with how the transaction is recorded in 1C. This procedure helps distinguish an input error from a configuration, data exchange or program algorithm error. If an incorrect date was entered manually, correct the details in accordance with the procedure established by the organisation, repost the document and check the result. If the value was received through data exchange, compare the data in the source and receiving systems and check the transfer rules. A manual correction made only in the receiving database may remain in place only until the same data is loaded again. For an individual entrepreneur who is not required by law to maintain accounting records or prepare financial statements, the date on which income from work or services is recognised is determined by the acceptance certificate or another document confirming their completion: the income is recognised in the period in which such a document is signed (Article 725 of the Tax Code of the RK). Therefore, moving the date of such a document to another period may affect the IE’s tax accounting. If the error recurs for different users or arose after an update, it is useful to provide the 1C specialist with: - the name and version of the configuration; - a description of the action after which the error appears; - an example of the document without unnecessary personal data; - the expected and actual results; - information about a recent update or configuration changes. During the technical analysis, the working date settings, user permissions, document sequence, data exchange rules and changes made after the update are checked. If the cause is a software error, the specialist determines whether a fix is available for the configuration version being used. The production database is corrected after a backup has been saved and the correction has been tested on a copy of the database, if this procedure has been established for the organisation’s information system. How to reduce the risk of the error recurring For daily work, it is useful to establish a standard control procedure. Before posting, the accountant checks the date against the source document or another supporting document; after posting, the accountant checks the result in the accounting registers or report; and before closing the period, the accountant checks documents with unusual dates and an incorrect sequence. Such controls help ensure that the information used to calculate taxes and prepare tax returns is systematised (Article 202 of the Tax Code of the RK). User permissions are also relevant. The ability to modify documents from previous periods should be granted to employees in accordance with their job responsibilities. This reduces the risk of accidental corrections after reports have been prepared and makes it easier to determine the reason for a change. Updates and customisations should be performed after a preliminary assessment of their impact on the production database. Following technical changes, standard transactions should be checked using test examples: creating and posting a document, generating a report and exchanging data. For a customised configuration, the verification procedure is established taking the changes made into account. If the question concerns not the calendar date in the program but the recognition date of a specific transaction, the solution depends on the type of document and the taxpayer’s status. For example, the special rule on recognising income as of the date on which an acceptance certificate or another supporting document is signed applies to IEs that do not maintain accounting records or prepare financial statements (Article 725 of the Tax Code of the RK). In other situations, the date of recognition is determined based on the substance of the transaction and the rules applicable to it. Frequently asked questions Why is the document not visible in the report for the selected day? — Check the document date and posting status, the reporting period and the filters applied. If the document was received through data exchange, also compare the date in the source system with the result of the data load. Can I simply change the date of a posted document? — Before making the change, assess its impact on related documents, the closed period and reports that have already been prepared. After making the correction, repost the document and check the register entries and final figures. Why does 1C enter a date other than today’s date? — The value may be determined by the session’s working date, the date of the source document or data received through an exchange. The cause is determined based on how the specific document was created and the database settings. What should I do if the error appeared after an update? — Record an example, the configuration version and the sequence of actions. Then check whether the error can be reproduced on a copy of the database and whether a fix is available for the installed version. Which article of the law regulates a day in 1C? — There is no separate provision concerning a “day in 1C”. Accounting data and accounting documentation are relevant for tax accounting purposes (Article 202 of the Tax Code of the RK), while the specific rule governing the recognition date is determined by the type of transaction. For income from work or services earned by an IE that does not maintain accounting records, the period in which the acceptance certificate or another supporting document is signed applies (Article 725 of the Tax Code of the RK).
