How to debug RFC in Background Task (with) Destination As Separate Unit?

[Former Member]

Dear Gurus, I have a specific requirement to debug RFC for bellow

Scenario:-

We create pro forma Invoice using VF01 in ECC system and gets Transfer to GTS System.

Issue:-

While Debugging we arrive at RFC which transfers Invoice to GTS system , I changed the setting to Update debugging to capture this task in SM58.

When I run SM58 i can see the the task and when I choose menu edit + debug LUW for that background task I am getting a message that "RFC does not exists".

I had put external breakpoints in this FM in GTS system but still I am not able to debug this.

The user id which is being used in RFC destination is of type Interface user.

Please let me know how can we debug in such scenario?

Best Regards,

Prashant
