Dear All,

I am working on Agreegated planning SNP, for this i have created Location_product Hierarchy .Selected the standard data view "SNPAGGR" , selecetd the selection "APO Location Product Header" and added the Product and Location , But i am not able to Load it in planning book, it is giving the Error "Incorrect call from FB /SAPAPO/REL_GET_INFO".
