T-RFC are not delivered to source system - dump with "Access using NULL object reference is not poss..."

Hi.

I try to setup a test environment and connect an new SAP BW 7.31 to a IDES Source. Everything is fine but the Request Idocs is not delivered to source system because of an error in T-RFC queue. It seems that the target system is not set.

If I try to process the Idoc in BD87 I can see the short dump that there is a NULL pointer exception. It appears during a check if all Idocs are from the same sender (see screenshots attached). I also found some other people having this issue but no solution. Because it is a self made system for testing I have no basis administration behind to solve this. 😊

Thanks in advance,

Nils
