maybe this question was answered in the past.
When using AO workbooks (they're saved on BI platform) I'm not able to use variants. The authorization object S_RS_PARAM is maintained on the acc. ABAP-Stack of the BW System. When I'm using a single BW query I can use the variant and I can save the variant.
I've tried it with latest available AO-Version and patchlevel but I'm missing the function to use variants on combination with AO workbooks which are saved on a BI platform as well ;-(.
THX and best regards, Clemens
