This message means that in the line of the tabular section "Goods" the unit of measurement was automatically cleared by the system because the name of the unit of measurement specified in the received EIF did not match the value stored in the reference book. As a rule, the reason lies not in the unit of measurement itself, but in the item to which it is linked.
Cause of the error
This most often happens when the item specified in the EIF is marked for deletion. The deletion mark conflicts with the document check (validation): the system sees that the line refers to an object considered deleted, and as a result cannot correctly match the unit of measurement — it is simply cleared.
How to solve
There are two options:
1. Remove the deletion mark from the item referenced by the document line. After that, the unit of measurement should be pulled in and pass the check correctly.
2. Select another item of the same type instead of the one marked for deletion — that is, replace the position in the "Goods" line with a similar item without a deletion mark.
Either of these methods eliminates the conflict, and the document can be posted without errors.
Frequently asked questions
Why exactly is the unit of measurement cleared instead of a direct error about the deleted item being displayed?
Because the system first tries to match the name of the unit of measurement from the EIF with the value in the database. If the item is deleted, the matching breaks, and the visible consequence is precisely the clearing of the unit of measurement field — although the root of the problem lies in the item itself.
Do I need to fully restore the item or can I just remove the mark?
It is enough to remove the deletion mark — the item itself is not physically deleted from the database, the mark only flags the object for subsequent deletion. If the mark is removed, the item becomes "alive" again and available for use in documents.
What if the item still needs to be deleted?
In that case, it is better to select a similar item of the same type for the document line, and leave the item marked for deletion as is — this way you will avoid the conflict in the current EIF.
