It's possible that the payment documents sent fall under the scope of non-supported scenarios, for example, cross-company Payment Remittances, in which there are more than one COMP_CODE value in different items. In these cases, the export program doesn't handle these documents correctly. Check the Restrictions page to identify these scenarios.

For Managed Gateway AddOn SP versions older than SP11, there was an error with the Remittance program in the ERP side where the BUYERITEMPAYABLEDATE was not populated, therefore a few data fields like PayableDate was not populated.

The payment document must be created respecting the Restrictions.

For Managed Gateway AddOn SP versions older than SP11, the issue was fixed by implementing the following SAP Notes in the ERP:

2934127 - ARBCIG_REMITTANCE_EXPORT program creates payload with irrelevant documents - SAP ONE Support Launchpad

2925871 - ARBCIG_REMITTANCE_EXPORT program fetched incorrect invoice fiscal year for a record under remittance items - SAP ONE Support Launchpad

2849787 - ARBCIG_REMITTANCE_EXPORT program was not updating the credit memos on SAP Ariba Procurement solutions - SAP ONE Support Launchpad

2975005 - Incorrect COMP_COD in items of the REMITEMS section was sent from SAP Ariba Procurement solutions during remittance export - SAP ONE Support Launchpad

After applying the corrections in the ERP system, resend from the ERP system all the remittance data that has failed.

It's strongly recommended, to avoid any further issues in the integration, that a supported Managed Gateway Add-on SP (Support Package) release is adopted.
Only the latest (N) and previous (N-1) versions of the Add-on are supported. For more information, refer to Where can I find the list of supported SAP product versions for Ariba Cloud Integration Solutions?
