Hi R.K.;
Thanks for your reply;
Yes, this is what the help of the message suggests, however, I could not find. Not wanting to spend a lot of time in research, I changed completely the setting by using the standard MRESCR/MRESCR01 messages (instead of the Z *) and a processing code I linked to the module function IDOC_INPUT_MRESCR. It seems to work.
I continue my tests
Thanks and best regard.
