3749938 - Why Import Batch Data event is not triggering in SAP Ariba even though SAP Integration Suite, managed gateway for spend management and SAP Business Network Transaction Tracker shows completed?

I am loading master data Import Batch Data to my SAP Ariba parent realm via SAP Integration Suite, managed gateway for spend management and SAP Business Network. Even though the Transaction Tracker shows the transaction as completed, the Import Batch Data event under Data Import/Export in SAP Ariba is not triggered or updated. My system returns a 200/202 response, but the data is not processed in SAP Ariba.
