Need file in UBL format

Summary:

CMK is a seeded functionality for sending AR transaction which has print enabled at transaction level and customer site has generate bill set to Y. In the custom requirement, third party system needs all the AR transaction irrespective of generate bill flag so that they can archive transaction which has generate bill = N and send to the respective trading partner those transaction which has generate bill=Y (these will also be archived).

Through our analysis CMK cannot accommodate it , it can only add addition information in the payload. Adding a DFF on the transaction is not an option as it would mean altering all the front systems (there are many).
