Hi'
We use assembly processing.
The field "Reason to rejection" is used to "close" completed SD-line items (do not ask about this please).
The short version of mine: 
When the line item is completed I would like the assigned project automatically to have status Tecnically completed, instead of a Deletion Flag.
(I know a lot of considerations should be done!)
Where can I change the behavior from setting Deletion Flag and instead put Status Tecnically completed at the assigned project?
Thank you in advance for answer 
Best regards
Lone
