No data loaded through BW showed in BPC

Hello.

I am new to the community and forum and excuse myself beforehand if this info is already here. I could not find it.

I am working with SAP BOPC 10.0 and Netweaver 7.3.

The question is I get no data in reports when executing them from BPC, either in web or in excel (with EPM add-in) if data is not loaded from excel too, through EPM add-in, and I can't find why.

If I load data through EPM (using excel as upload form) then I can see it in reports. If data is loaded from SAP R3 or flat files through different means I get no data in web or excel reports.

If additional info is needed to help me just ask for it.

Thanks for reading.
