The 'Enable Process Attachment Scripts' setting in the IBM Rational Change and Configuration Management Application Administration Advanced Properties is not enabled.

Resolving the problem

There is a setting called 'Enable Process Attachment Script' which needs to be turned on in order to use scripts for attribute customization. Below are the steps to turn on the setting. These steps are extracted from the article, Attribute Customization: Using Scripts for Attribute Customization .

Using Script for Attribute Customization:
To use scripts deployed as process attachments, you need to enable this functionality:

  1. Go to administrative page of the Change and Configuration Management Application server
  2. Open the Server tab.
  3. From the left side-bar open Configuration -> Advanced Properties
  4. In the Work Item Component, find the 'Enable Process Attachment Scripts' property and set its value to true.

Alternatively you can add the following line to

# Allow to use scripts deployed as process attachments
