Renumbering Activity ID in Primavera P6

By default activity ID in Primavera has a format like A1000, A1010 and so on.


How about we can make the ID more meaningful.

For example we can change the “A” letter to show the WBS which they belong to.

First you will select all activities you need to renumber.


Go to Edit -> Renumber Activity IDs


Select “Auto-number”. And enter Prefix like “FDN” for Foundation.


Click OK. Now you can see the IDs have been changed.


You can do similarly for other activities then we’ll have a meaningful activity ID.
