Automatic Retention Event Not Generated Through Project Process Configurator

Summary:

We have configured the Project Process Configurator in PPM to automate retention calculation based on the percentage entered in the Contract Line DFF. As per the setup, the system should automatically create a retention event when an invoice is generated.

Example:
Contract Line Value = 1000
Invoice Amount = 100
Retention % in DFF = 5%
Expected Retention Event = -5

However, the system is not automatically creating the retention event as expected. The configuration appears correct, but the functionality is not working. Please assist in reviewing the setup and identifying the issue.

Additionally I have attached the reference file of configuration.
