GL account balance for Non Leading Ledger

Hi,

I am trying to get GL account balance for Non leading ledger.

I am able to get Balance sheet GL account balance  for leading ledger using 'BAPI_GL_GETGLACCPERIODBALANCES', but I am unable to do so.

For P&L GLs, requirement is to get internal order wise account balance. I am able to get GL balance for leading ledger using documents in BSEG.

Any idea on how we get GL balance for non leading ledger?

Thanks in Advance.
