The scenario is as follows: I'm having many subprojects that look almost exactly alike (i.e. only the names of some tasks differ but the structure is the same). Thats why all Project Files are usually copies of one single template. To generate a simple overview of the key tasks in every subproject I'm generating a master project with all subprojects included as linked, read-only subprojects.
The problem now is that Ms Projects is not able any more to distinguish between the same task in i.e. subproject a and b (and all that might follow). More specifically: If I add Task 1 from Subproject a to the timeline and then try to add Task 1 from Subproject b to the timeline the "Task 1" entry in the timeline vanishes.
I suspect there are IDs of every Task internal to MS Project that are duplicate in the master project because all subprojects are copies of the same template.
Does anyone know of this bug, a workaround (other than generating all subprojects manually wothout copying) or has maybe a hint what I'm doing wrong? Thanks and best regards!
