How to Group Security Payment by Transaction

Hi Expert,

We need to group security transaction by transaction number in payment run as our bank statement is showing trades seperately. Within a transaction, they are charges/expense which should grouped together in same transaction. In Payment Detail tab of transaction creation (FTR_CREATE), the grouping definition option 9 - Only flowas from a single financial transaction is only available to money market transaction. In security transaction, it's still didnt grouped. Securiy ID and Security account sometimes could be same for different transaction, so i can't group by this option as well.

Any idea how can i handle this requirement ?

Thank you.

Regards,

Oscar
