Hi Nikhil,
please do an 'xSearch' for all notes using the search criteria VAL_SID_CONVERT, you will find endless documentation on this issue and will undoubtedly find the solution. Focus your analysis on the notes in the component areas BW-BEW-OT* and BW-WHM-DBA-ODS.
I believe these notes will reveal the solution,
Thanks,
