The reason why the write-off document for goods "hangs" on 1 unit out of five is that when the goods were received, the postings did not reflect tax accounting (TA). Because of this, a discrepancy arises in the system between accounting (AC) and tax accounting, and during write-off, part of the quantity "cannot find" the corresponding data in TA.
How to fix it
To resolve the issue, you need to synchronize the accounting and tax accounting data for this item:
1. Enable the accounting for temporary differences on corporate income tax in the accounting policy settings.
2. Enter opening balances to adjust the tax accounting for the problematic item — that is, add to TA the information that was not reflected upon receipt.
After this, the accounting and tax accounting data are aligned, and the write-off document is processed correctly, without "hanging" units of goods.
Frequently Asked Questions
Why is it exactly 1 unit that is not written off, while the other 4 go through normally?
The discrepancy in TA could have arisen for a specific batch or part of the receipt — for example, if the receipt was registered in several lines or at different times, and the tax accounting was not fully reflected. The program writes off the quantity for which there is correct data in both AC and TA, while the "problematic" balance blocks the posting.
Should the accounting for temporary differences be enabled permanently or only to fix the issue?
If the organization maintains tax accounting for corporate income tax and discrepancies between AC and TA are possible, this setting should be kept enabled permanently — it is a standard mechanism for correctly reflecting such situations, not a one-time measure.
How can you tell that the cause is specifically the absence of TA upon receipt, and not something else?
You should check the postings of the receipt document: if they contain no tax accounting data (only accounting amounts), this is a clear sign that TA was not generated, and the correction should be made specifically through entering opening balances.
