Hi Sudhir,
It will depend on your system and DataSource where the DataSource field assignments to InfoObjects can be found. It is dependent on the data staging technology used. Nowadays Business Content is often migrated to 7.x and you can find the assignments in other tables.
3.x DataSource:
T/code SE16
Table RSOSFIELDMAP
7.x DataSource:
T/code SE16
Table RSTRAN and RSTRANFIELD
In table RSTRAN you must select the field TRANID based on OBJVERS = 'D', SOURCETYPE = 'RSDS' and SOURCENAME = 'OFI_GL_14*' (note the wildcard * at the end).
You can find the assignments in table RSTRANFIELD using the TRANID. There are groups of DataSource field and InfoObject based on RULEID.
Best regards,
Sander
