Updating Existing Data When You Import an XER File Back Into P6

By default, when you import an XER file back into P6 and update an existing project, it does not update certain fields. That means that if you made changes to any of these fields in the file you are importing, the data is not updated in the existing project.

The fields that P6, by default, does not update are:

Resource Codes
Resource Code Values
Rates
Resources
Short Names
Calendars

To update the above fields when you import an XER file back into P6:

In P6, when you get to the Update Project Options page in the P6 Import wizard, click Modify.
Click in the Actions column for any field you want to update that has Keep Existing and change the setting to Update Existing.

You have to complete the above steps every time you perform the import.
