Error (WIS 10901) while creating a webi report against SAP data source


While creating a webi report against a universe created using Infocube/Bex query (basically SAP data source) get a error message -

A database error occured. The database error text is: A runtime exception has occured. (License key check failed. Check that you are licensed to access SAP data sources). (WIS 10901).

Any clues whether this is a license issue or something else?
