Brendan gave a number of options to explore.
It would be nice if you could write a proper question, with some context, and at least what product you are using.
I imagine you aren't using FDI, but building a report on Fusion. In that case, this is not the right forum: Fusion data questions should be posted in https://community.oracle.com/customerconnect
@Kalyani-Oracle , please use this specific forum General Ledger & Intercompany — Cloud Customer Connect to ask your question. You can search also for already answered questions, and it might help you get the answer for your question.
Hope it helps!
