hello
yes it helps, but ...
the main issue is:
using production orders means to use an object with a state. this state (open, released, finished, ...) can change.
changing this state means: create a new production order with new state, copy the attribute values from old PO to new PO, delete the first one.
so it looks like that zetadocs does not check the state change, because zetadocs does not know anything about the new PO. But this is the aim: To have the same zetadocs document links in the new PO (with new state).
i tested a lot: the zetadocs document links are lost on changing the state.
regards
