Hi ​@negar.tornros ,

Please check the total net amount you are paying for the supplier 10000301. This happens when your net payment amount is negative.

Hi ​@Sugandi Nadeeshika 

The total net amount is positive: 

Are both lines in payment proposal connected to the same payment method?

Hi ​@Ralph Gericke 

Yes they are:

Hello ​@negar.tornros,

In ISO 20022 pain.001.001.03 (Credit Transfer Initiation message), negative values are not allowed in monetary fields.

So, the correct way of working is create a Supplier Offset between those two invoices and then create the proposal for the remaining amount of the debit invoice.

Normally, I recommend to use the “Offset Possibility” option in Supplier Payment Proposal. Then user can easily identify which invoices can be offset before create the Payment Order.

Hello ​@negar.tornros 

In order to achieve this, you must prepare a structured payment. Because only in the structured format, you can inform the supplier about remittance details.

Go to Payment Institute → Payment Methods per Institute and then Format Specific Info per Institute.

Change payment parameter to Structured Payment and Credit Note Grouping for Non-SEPA payment. 

The alternative is to make an offset, print offset details and send to supplier so they will be aware of offset transactions. Printing the offset proposal is available on Supplier Offset Proposals.

Hope this helps
