Is it possible to delete M version of an InfoObject ?

I would like to delete the 'M' version of 0BPARTNER, and just keep 'A' and 'D' Version.

Is there a way to do that ?

Delete some rows from RSDIOBJ and other tables ?

I activated 0COORTYPE and 0CCTR_IBV from business content,

and BW had updated 0BPARTNER (with a BW V7 version) because BPARTNER.

So I want to delete the M version of 0BPARTNER (BW V7) and keep the 'A' Version (BW V3).

Thanks for any help or advice
