• Message text: Ref. material for copying may be missing - check log

What causes this issue?

When you tried to find copy references for the necessary material
master segments, it is highly likely that not all the segments could be
created.

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?

1. Check the possible missing data using the "missing material master
segments" function in the "Assortment" menu. A detailed confirmation is
made there.
2. Maintain the reference materials for each material group to such an
extent that this error can no longer occur.
3. Alternatively, you can make another attempt to create the possible
missing segments via the menu "Assortment - Mass maintenance - Generate
missing material master segments". The precondition for this, however,
is that you provide suitable copy references for this purpose, by
firstly maintaining the reference materials per material group, for
example.
