In 2026, a loading or exchange error in 1C is checked based on the stage of the operation, the affected object, and the data after the processing of which the message appeared. Article 833 of the Tax Code of the Republic of Kazakhstan establishes the procedure for reviewing applications and claims for the refund of excess VAT submitted before 1 January 2026, rather than rules for diagnosing the infobase (Article 833 of the Tax Code of the Republic of Kazakhstan).
What an error in 1C data means
An error message does not always mean that the infobase data is corrupted. It may appear if the program receives a value of an unsuitable type, is unable to match an object reference, or does not receive the expected response when accessing an external service.
It is important for the accountant to record not only the message text but also the operation during which it appeared: loading, unloading, exchange, publication of a commercial offer, or user matching. The same text appearing during different operations may be caused by different data and settings.
In practice, the following messages may appear, among others:
- “Error retrieving data through the 1C:Business Network service. Please try sending the data later”;
- “The data type is specified incorrectly.”
The first message should be examined in the context of sending or publishing a commercial offer through an external service. For the second message, it is necessary to determine which object was being processed and at which stage of the exchange the program detected a data type mismatch.
Until the cause is established, the exchange should not be repeated multiple times without investigation. First, save the error text, identify the affected operation, and check the attributes on which its execution depends.
How to check data in the event of a 1C:Business Network failure
If the message about retrieving data through the 1C:Business Network service appeared while working with a commercial offer, the check should begin with the offer itself and its publication parameters. The name of an internal procedure or form should be recorded only if it is displayed in the detailed error text or technical log.
Practical procedure for the accountant or responsible user:
- Save the exact message text and take a screenshot.
- Record which commercial offer was being sent and on behalf of which organization the operation was performed.
- Check that the attributes and parameters used for publication are completed.
- Make sure that the required commercial offer is selected and that all values mandatory for sending are entered correctly.
- Try sending it again later, as suggested by the program message itself.
- If the failure recurs, provide the specialist with information about the commercial offer, sending time, user, and displayed technical details.
The phrase “try sending the data later” permits another attempt after a pause, but it does not in itself identify the cause of the failure. Before sending again, check the offer record, publication parameters, and connection availability. This helps distinguish a temporary connection failure from a data entry error.
After successful sending, make sure that the offer has actually been published and has not remained in the queue with an error status. The disappearance of the message from the screen does not in itself confirm that the operation has been completed.
What to do when the message “The data type is specified incorrectly” appears
When the message “The data type is specified incorrectly” appears in “Accounting for Kazakhstan” or “Payroll and HR Management for Kazakhstan,” first establish the context: unloading, loading, object matching, or another operation. The message text alone cannot reliably identify the specific directory or internal procedure in which the mismatch occurred.
If the detailed error description specifies the “Users” directory or the message appeared at the user-matching stage, begin by checking the user records and references between the source and receiving databases. If another object is named, diagnose that object and its related attributes.
Recommended checking sequence:
- determine at which stage the error appeared—during unloading, loading, or matching;
- record the object specified in the detailed message text or technical log;
- check whether the corresponding directory item exists in the receiving database;
- pay attention to empty, incorrect, or unrecognized references;
- check the attributes of the records involved in the transfer;
- do not change data types or object structures without a backup and the involvement of a specialist;
- after correction, perform the exchange using a controlled data set and check the result.
If the error appeared after a transfer between infobases, the specialist will need information about the source and receiving configurations, their versions, the exchange scenario, and the stage at which the operation was interrupted. The accountant should also check the completeness of the result: the presence of documents, directories, and related items that should have been transferred.
How to organize safe work with data
Before loading again or making a technical correction, it is advisable to create a backup copy of the infobase using the method adopted by the organization. This is especially important if references are to be changed, an import is to be repeated, or an array that has already been partially loaded is to be processed.
It is useful to keep a brief incident log. It is sufficient to specify:
- the date and exact time of the failure;
- the operation during which the message appeared;
- the exact message text and its detailed description;
- the configuration name and version;
- the object or document with which the user was working;
- the checks performed;
- the result of the repeated exchange.
Documents, users, or directory items should not be deleted merely because they are mentioned in the diagnostic information. First determine which attribute, reference, or parameter contains an unsuitable value. Deleting an object may disrupt links between data and may not eliminate the cause of the message.
After the error has been resolved, verification should include more than confirming that the message does not recur. Compare the number of transferred objects, open selected documents, check the related directories, and make sure that the operation received a successful final status in both databases or in the external service.
Frequently asked questions
What does the message “The data type is specified incorrectly” mean? — The program detected a value that does not match the expected type at a specific processing stage. The object and attribute are identified from the context of the operation, the detailed error text, and the technical log.
Can I simply try sending the data to 1C:Business Network again? — The message suggests trying again later, so sending the data again is permitted. Before doing so, check the attributes and parameters of the commercial offer and then check the final publication status.
Do accounting entries need to be corrected when this error occurs? — An exchange message alone is insufficient to conclude that there is an error in the accounting entries. First check the object named in the diagnostic information, its attributes and references, and the parameters of the operation being performed.
How can I tell whether the exchange was completed successfully? — It is not enough to see that the message has disappeared. Check the presence and completeness of the transferred objects, the correctness of their links, and the final status of the operation.
What should be provided to the 1C specialist? — The exact error text, message details, configuration name and version, the operation being performed, the affected object, the time of the failure, a screenshot, and a description of the checks already performed.
