We have already setup SAP authentication and SSO between ECC6 and BI4, e.g. to run CR 2011 reports with data based on ECC infosets, or BEx (operational BI on ECC). ECC is the main point of entry for users, so ECC user accounts and role imports are used in BI4.
Now if we add BW to this, with Crystal or WebI or Analysis OLAP sourcing data from BW, can we still leverage detailed authorizations in BW on the corresponding BW user - with user accounts and role imports in BI4 still being ECC-based?
