Background Extraction Job in SAP does not stop when stopping the extraction in SSIS

Background Extraction Job in SAP does not stop when stopping the extraction in SSIS. After stopping the package in SSIS the job in SM37 is still running. 

Ending the process in SSIS does not end the background job in SAP, and the job is waiting for Xtract IS to collect the data.

End the related background job in SAP in the SM37 manually. Xtract IS has no possibility to end the process after the package is stopped by SSIS. 

This behavior does only occur when using Xtract IS. The Abort in the other tools, like Xtract Universal, is ending the process. In Xtract IS, this is technically not possible, because the leading process is SSIS.
