prim12262:Can specific WBS elements and activities be exported to an XER file?

Create two separate projects, with inter-project links.  In this way, the activities or WBS nodes you wish to export can be put into a separate project so that only that project is exported.

Note:

It is important to ensure that the “Ignore relationships to and from other projects” scheduling option is switched off when working with inter-project links.

In the example below, since I wish to export only activities B1000 and B1010, I can export only Project B.

In version 5.0 and later, activities which have inter-project links when they are exported to an XER have External Early Start and External Late Finish dates which act as constraints placed against the activities.  These dates ensure that when the project is scheduled in a database other than it’s original database, the inter-project links in place at the time of export will be taken into account in the schedule.  The Start and Finish columns for these activities show an asterisk (start) to indicate that the activity is constrained.
