We have a USD subsidiary and a NTD subsidiary. For the NTD subsidiary, we just upload the monthly trial balances in NS. I'm wondering if I can record the one-sided intercompany AR forex revaluation in NS. I keep getting the "elimination settings" error. If not, how do clients deal with this issue?

Yes you can but you need to customize the form of your JE need to show the field to subsidiary on the header and eliminate on each line

I already did but I'm still getting an error. Do I need not to populate the Name column?

If it’s an Ap/Ar account you need to populate the name

Ohhh it's working now. Had to populate all of them.
