Hello Sven,
Thank you for the reply. I added more info on the topic.
I think you are right since it's the starting point that's giving me problems. I had also wondered if I shouldn't go to back to the developer and ask him to return the output immediately to HRS.
I wasn't sure that it would be possible for them (or not a very "clean" way to develop).
In any case, if the output is directly put into HRS (what I was trying to do), it would not inhibit the decision making and it allows me to put the information into variables at the precise place in the schedule when needed to generate the text string (no real need to store it in a time type, I think).
Kind regards,
KRis
