Please let me know how we can implement the below scenario.
In a single mapping,more than 500 sources
(legacy,VSAM,relational) will be loading into only one
target. Whenever I retreive the data(any record) from
target, i need to find the details that the record belongs
to which source.

Thanks in advance..

Answer Posted / arnab

create a system where you can identify a source with an
ID.you may call it as datasource_num_id , build a cross
reference table to store all tis information , in the map
you can use this cross reference table to get the ID and
populate this id in ur target table
