In Primavera we can use ‘Renumbering Activity ID” function to modify Activity ID Prefix. How about we want to modify Suffix.
I will show you how.
We have a simple project with default activity ID like this
First we go to Tool -> Global Change
Click on New button
In “Then” section:
Then enter the Suffix you want to add. For example “FDN”
Click on “Change” button.
P6 will show you a preview of the change. Click on “Commit Changes” button.
Now you can see there is “FDN” letter in your Activity ID.
