Hi
My organisation uses tax invoice approval journals as part of a third party AP automation system Exflow and we regularly receive this posting error.

I have used tax invoice approval journals in other organisations and I have never seen this error before. To date our implementation partner and Exflow support team have been unable to resolve this. If I manually key the exact same invoice in the tax invoice register and select the voucher into a tax invoice approval journal and add the same breakdown of expense lines I do not receive this error. Which suggests the problem is with how Exflow loads the tax invoice approval journal, but they have not been able to solve.
Has anybody else ever encountered this before and do you know what it means and how to resolve this? For information we do use ledger accrual schemes on some invoices. But I have not seen this error yet on an invoice with ledger accruals. The GST balances the invoices are in local currency with no exchange rate conversion.
Any suggestions as to the possible cause will be gratefully received.
Regards
Simon
