The SHDB was initially done without "simulate background mode" it seems.
Then, the issue has been identified during the tests when executing the program in background (via RBDAPP01).
After analyzing the SHDB we saw that a screen was not called in "simulate background mode".
And was displayed without selecting "simulate background mode".
As we will have to process these idocs/call transaction in background, we need to find a way to have this screen called even in background mode.
We tried to change some options of CTU_PARAMS uring the call transaction (DISMODE, DEFSIZE, NOBINPT,...) but we did not find a solution yet.
Thx for the help.
Newbie.
