DMT - Cash Receipt/Payment

Hi everyone, trying to DMT import some payments in AR Cash Receipt but am getting the following error:

Company 165086 GroupID TESTDMT CheckRef 100582 Table: CashHead Msg: Cannot update Invoice Number.

Am I missing something in my upload template?

I’ve played around with it, and even if it does create a payment the amount is not applied at all.
Tried similar formats in both the Payment an Cash Receipt Combined menus.

Thank you!

Hi Shindee,
Were you able to resolve this? We can import a payment for a single invoice, but if there are multiple invoices to be paid, we don’t understand how to connect the single payment to multiple invoices.
Thank you!
