Optimize BAPI calls in loops by reducing frequency, batching requests, and leveraging asynchronous processing.

• Batch Processing: Instead of calling BAPI for each record, collect multiple records and call BAPI once. For example, if processing 100 records, send them in a single BAPI call.

• Asynchronous Calls: Use asynchronous BAPI calls to allow other processes to continue while waiting for the BAPI response, improving over...read more
