Hi Mani,
at BW sider, Table - RSOSFIELDMAP, try to see the contents.
there enter IOBJ - info object name as 0BP_REL* and execute it.
see are you able to see display data or
use above table and pass OLTPSOURCE - <enter your data source name 00BP_RELATIONS_ATTR>, you may see ecc field and bw related info objects. in that you can see 0bp_relations there or not.
Thanks
