I am trying to update the Partner Information in Sales Order. I need to update the Forwarding Agent information (CR) in item level of Sales Order. But when I tried to change it using the BAPI_SALESORDER_CHANGE function module, I got the message, Sales Order is saved. But it is not getting updated. I am using BAPI_TRANSACTION_COMMIT function module also. I am passing all the required update parameteres too.
Any assistance in this regard will be appreciated.
