How to add Batch Source context to RA_CUSTOMER_TRX DFF?

Summary:

We try to use transaction header DFF with batch source context.

Initially we have defined batch source contexts and leave the select action to user. However, it should be automatically assigned after transaction source selection.

SQL default type let us to fill the query in Default Value field but when we tested it on AR transaction page, it does not work as expected.

If we choose default type as Parameter as below ss, it gave below error. Is there any way to use it like we have done it in EBS?

The default value BatchSourceSeqId is not valid. (FND-2908)
