Journals under Secondary ledgers to be created based on DFF used in Journasl lines of Primary ledger

Hi,

We are on Oracle R12.2.4

We have one Primary ledger and one Secondary ledger. All Segments of both Primary and secondary are same except Natural account segment.

We have one to one mapping for all accounts of Primary ledger to Secondary ledger.

There are certain scenarios, wherein users want to enter a Journal line in Primary ledger with Secondary ledger Natural account value in DFF.

Once we post the journal in Primary ledger, journal gets created in Secondary ledger based on the mapping defined.

But instead of mapping, Our requirement is that system should use the accounts as mentioned in DFF (of Primary journal line) for journal lines created in secondary ledger.
