Caution: Full product has several bills of material

What causes this issue?

You want to carry out a physical inventory for a material which is
related to an "empties" material. For this material, several BOM's with
different units of measure exist. If there are inventory differences, a
differences posting is carried out for the items (empties) of the BOM
for which a unit of measure was entered. This can lead to incorrect
postings because the empties of the other BOM's are not taken into
account.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Check the postings for the empties on the basis of the physical
inventory documents. In the case of incorrect postings, adjustment of
the stocks is required by way of a physical inventory of the "empties"
material affected.
