Hi Johanna,
If you use MDG you can use WebDynpro applicatin USMD_CHANGE_DOCUMENT (and maybe also if you don't use MDG). The analysis however can only be done 1 attribute at a time and you cann't use selection masks on the material number.
So if you would have MAT1, MAT2, MAT3 you can't select with * or MAT*. However you can put in multi select MAT1, MAT2, MAT3.
It will always select the changes made on the Change request, but you can also include the change documents from the active area (what you see in MM02 and MM03). It the result list it is clear where the change is done MDG or PP (origin of change).
So it is not ideal but maybe better then 1 material at a time using MM02.
Cheers,
Henk.
