table for mapping between DSO and Datasource fields ?

Hi,

I am looking for a table in BI which has the

1) mapping between DSO and Datasource and

2) mapping between DSO & INfocube. We have transformation between these and I need to find the table where it has the mapping of the field names between the source and target objects.

Is there any standard table for the same ? I appreciate it, Please reply.

Thank You,

DR
