This error most often occurs due to a discrepancy in the ESF amount: if the document amount in the 1C database differs from the amount already recorded on the server (ESF IS), the notification will be rejected.
What needs to be done
Check the amount of the electronic invoice (ESF) for which the VAT notification is being sent. Compare it with the amount registered on the server. If the amounts do not match — this discrepancy is exactly the reason for the document being rejected.
If a difference is found, the data needs to be brought into alignment: either correct the amount in the database, or determine which amount is correct and make corrections so that the values in the database and on the server match. After that, the notification can be resent.
Frequently Asked Questions
Why can the amount differ in the first place?
The discrepancy occurs if the document in the database was modified after being uploaded to the server, or if the data was initially entered incorrectly.
What should I do if it's unclear which amount is correct?
You need to check against the original ESF on the ESF IS server and compare it line by line with the document in the database to find the specific discrepancy.
