Diagnosis
A BDOC field - not coming from the root segment - is used in aSelection condition, and no Selection module is specifiedin transaction BWA1.
Without specification of a Selection module a generic modulewill be created. But this module is not able to handle otherconditions than those refering to fields of the BDOC root segment. Thiswill cause an runtime error during the extraction.

Procedure

• You can either change the Selection condition. Doing so, you can
only use fields from the BDOC root segment.

• Or you specify your own Selection module that overcomes the restriction
of our generated module.
