I connect R/3 to EP with WAS connection, tested in EP, it works fine.
I connect BW to EP with WAS connection and XMLA connection, tested in EP, it works fine.
In Visual composer, when I linked to EP,
if I select the BW system, I got all the infocubes on right hand side, no problem.
if I select the R/3 system, I got error message failed to connect to backend system, check user mapping and user priviledge, etc.
1. I know I do not have user mapping issue because if I had, I should got probelm when testing connection in EP beforehand.
2. what could be wrong? the WAS connection for R/3 - EP does not work for visual composer? Instead, I need connection of R/3 to EP from BI Java Connector (referring to BI kit's SAP connector/SAP query connection?)
3. If so, is the data from SAP Query connection limited to the scope of the SAP Query in the R/3?
Please advise.
