CNTL_SYSTEM_ERROR with BDC
We created a FM with Call Transaction BDC for HU creation for T-code VL02N. The FM is called in the Partner Profile for an incoming IDoc. The IDocs are processed correctly when triggered immediately. When the Partner Profile was changed to trigger in background, IDocs fail with error "CTRL_SYSTEM_ERROR".
Now when we switched the Partner Profile agian to trigger immediately, IDocs are erroring with the error: "Immediately processing not possible: Exception condition "CNTL_SYSTEM_ERROR" raised".
Anybody has any idea on this particular error.
