SAP Note 27347 - IN operator on multivalued charact. -> Syntax error

Symptom:

If you link a multivalued characteristic in the object dependencies to an IN operator (for example, "RR_DUMMY in (100, 200)"), the following syntax error occurs "28075 Character string required in inverted commas".

Cause and prerequisites

Multivalued characteristics cannot be linked by IN operators. See the syntax definition in the documentation for the variant configuration.

Solution
Use an OR operation. Example: RR_DUMMY EQ 100 OR RR_DUMMY EQ 200
