I need to pull Keyfigure1 and Keyfigure2 from 0MAT_ST_LOC.
What do you mean by this? Your KFs are in DSO and 0MAT_ST_LOC is also part of DSO.
If I create a multiprovider on DSO and 0MAT_ST_LOC and then assign
0MAT_ST_LOCis already there in DSO, right? Why again you are trying to create MP?
You have not explained clearly.
