Hi,
Are you trying to load data from EPM (using Package) into BPC models, then you can load data only from BPC BW (BPC backend) infoproviders like Infocube, DSO and infoobjects. You can not directly load data which is exiting in ERP , you have to stage your source data into BPC BW and load it in to BPC models.
Hope it helps...
regards,
Raju
