CALL TRANSACTION for MD47 in background

Hi Experts,

I have made a recording in SHDB and based on that I can make a CALL TRANSACTION to MD47. It works fine in online mode, but nothing happens when I run it in the background.

I have tried to flag 'Simulate in Background' during my recording in SHDB and also made sure it continues recording after COMMIT WORK, but the recording stops as soon as I hit Enter in the first selection screen.

Any ideas will be highly appreciated.

Martin
