Diagnosis
The ABAP query names its generated reports according to certainconventions. The names of all reports generated from queries start withthe characters AQ.
If you create your own report and its name begins with AQ, youinterfere with the work of the ABAP query since queries then cannot bedefined with certain names. Since the namespace for queries is not verylarge, every extra restriction is bothersome.

Procedure
Do not use a name beginning with AQ for your own reports.
