I use SD4.5 SP24 on APM. I create a change with diff. work orders on it via a change template. When after I open one of the WO an I open from the field change the related change than is the change not read only. I create now a change with diff. WO's who have predecessors. When I open a WO after and I want to open the related change from the field change on the WO, the change is read only. My question is : is it possible to modify this. I mean I want to be able to edit the change from the related WO also if they are related with predecessors.
