Error AR Invoice add“Reconciliation difference must be zero before recon

Dear Expert,

We have smoothly process with out error @ SAP B1 8.8 PL 14. But When we upgrade to SAP B1 8.81 PL 09 we are facing error. The process is

1 A/R down payment request (independent), as payment is being received in advance (earlier than Sales Order creation).

2. Incoming payment against A/R down payment request.

3. Sales Order > Delivery Order> A/R invoice >> in A/R invoice (while invoice creation) we call the payment made (in step # 1 and 2).

4. While we add this A/R invoice, we get this Error: u201CReconciliation difference must be zero before reconcilingu201D.

Please advice.

Regards
