Dear Raman,
I have sap_all authorization in ecc.
But at BW I have a limited authorization. I have to check with BI lead USER. But we were facing the same problem with BI lead user as well . I have added on the client side the same values in RSLOGSYSMAP at ECC and BW side . I have to check with BI Lead user. I will get back to you after checking.
Regards,
