Good day all. I am working on modifying our change ItemTypes (don't use the OOTB ones). I have been looking at the Simple ECO as an example. Our current changes are associated to a single document/part. So if someone is updating a drawing that affects a part, they would have to submit two changes, it gets worse if this affects multiple things. I would like to modify (or create a new ItemType) these changes to have the Affected Items tab. I have been testing this with a custom ItemType, but am running into problems with the Has Changes getting updated. I looked at Changes Pending in Part post and saw that there were a few Methods that I needed to look at. I modified the Methods PE_update_has_change_pending and PE_ChangeItemTransition to include my change ItemType, but my test document will not get marked as Change Pending. I tested the Simple ECO and it does mark the document. Thank you for any help you can provide.
