Ambiguities cannot be resolved without the analytic engine
The InfoProvider contains nested ambiguous joins that cannot be completely resolved in queries without the analytic engine (OLAP).
This situation occurs if an InfoProvider in linked in multiple directions, and the join fields for the several joins are not identical.
The InfoProvider can still be activated and used however. Where queries are made without the analytic engine (using list cubes, or the external data manager interface RSDRI for example) ambiguities can occur, despite the local aggregation.
