Maintaining Relationships during project import
I have Projects "A" & "B" in OPC.
Both projects are combined in Program "AB". Activities of Project A & B are linked using a relationship in Program "AB"
Project "A" is maintained in-house and Project "B" is a monthly import from an external contractor's P6 schedule using XML file.
Whenever Project "B" is updated monthly by importing the XML file from a contractor, we lose the relationship/links that are in between Project "A" & Project "B", that we created in the Program "AB"
Has anyone experienced this issue? What is the workaround?
My import settings are as shown in the screenshot below.
