Hi Subhash,
I set the parameters as suggested but it still doesn't work. When I move the pl order for the end product forward the dependng pl orders for semi-finished products remail in the same place. the same problem with operations in one pl order: e.g. when I move operation 30 forward the operations 10&20 remain in the same place, or if I move operation 30 backward all the operation 40 and up won't move.
Any suggestions what else I should alter to make this work?
and thanks again to both of you for your help!
I appreciate it!
best regards,
Pilvi
