We are going to start moving to using OWB in lieu of Microsoft Project and in reading the support documentation I read about copy/cut/paste of tasks in OWB. I know this is something you do not do in Microsoft Project if loading the project to CA PPM, but wanted to verify it is acceptable in using OWB with CA PPM.
Check if this helps
Copying tasks from one project to the other
Yes it is perfectly acceptable to copy anything or everything that can be copied from within the project WBS or from another WBS open in OWB or even from any spreadsheet (which has the same columns) to the "current" WBS and save back to CA PPM. CA PPM does not have grid copy paste yet so copy paste from other plans and Excel is a fast way of creating and editing WBS items. Copy special allows to copy also data which is not displayed.
