How to modify Activity ID Suffix in Primavera P6

Primavera P6 provides a built-in function to renumber Activity IDs and modify prefixes. But what if you need to add a suffix instead? Here’s how you can do it using the Global Change feature.

Scenario

We have a simple project with default Activity IDs like this:

Step 1: Open Global Change

1. Go to Tools → Global Change.
2. Click New to create a new rule.

Step 2: Configure the Rule

In the Then section:

• In Parameter select “Activity ID”
• In Parameter/Value select “Activity ID”
• In Operator select “&”
• In Parameter/Value select “Custom”

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.

Result

Your Activity IDs now include the suffix:

Key Benefit

This method allows you to quickly append custom suffixes to Activity IDs without manual editing, saving time on large projects.
