Hi All,

I'm using SCM4.1,I already run the forecast,The thing is i'm going to take data back up for planning area.

I already generated the back up cube form planning area(Generate info cube from planning area).In infosource i try to assign data source as my APO system means i can't select all my info object in Transfer structure,if i try to activate means its gives error please let me know ASAP.

Thanks in advance
