• Message text: Error occurred deriving representative material

What causes this issue?

Derivation of representative material &V1&.
The system was unable to find a derivation rule entry when carrying out
this derivation rule for the specified source values on data &V2&, but
could not find a derivation rule entry.
The derivation rule was set up in such a way that an error message does
not appear in this case.
On date &V2&, no derivation rule entry has the following source field
values:
&V3&
&V4&

How to fix this error?

Enter a derivation rule entry under <DS:TRAN.8KEO>Maintain Derivation
Rules/Entries</> for the specified specified source field values. See
also <DS:SIMG.SIMG_CFMENUORK18KEO>Derive Representative Materials</>.
Make sure that derivation rule entries are made for all valid source
field values.
If you do not want derivation to be carried out in all cases, you can
define the derivation rule in such a way that no error message appears
if a derivation rule entry does not exist.

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