Debugging DMEE

I've come across many posting on the Internet (via google search), people asking on how to debug a DMEE for payment program. One of the few suggestion was to create a user exit just before the node that we would like to debug and put our breakpoint there. It seems that SAP has built-in this feature without needing us to create a user exit (available in ECC 6, have no idea if this is available on prior releases). Here is how you can put your breakpoint without any coding.

1. Display your DMEE tree using transaction: DMEE_DEBUG.

2. Click on the node that you would like to debug.
3. Go to conditions tab, you could see the Set Breakpoint button. Click to set.

4. Run the SAPFPAYM and specified the payment run date/id, payment format etc. SAP will stop at the node which you point your breakpoint at, as in 2.
5. To remove your breakpoint, just run the DMEE_DEBUG again, there is an option to delete all own breakpoints or all.
