Hi All,We had a process model in Appian that was scheduled to send a report every Sunday at 11:59 PM.
Later, we discovered an issue with the report it was generating. Due to business requirements, we exported the process model, saved it locally, and then deleted it from Appian.
I had assumed that the scheduled activities were tied directly to the process model, so deleting it would stop the scheduled execution. However, this Sunday, we received an error stating:
Problem: An error occurred in executing an Activity Class.
Details: Process Model has been deleted. Process designer could not be retrieved
Recommended Action: Examine the activity class to correct the error and then resume.
Can anyone please help me to understand this scenario?

Thank you all!
Root Cause Analysis:
The process model was deleted on 30th September. The last successful run occurred on September 28th. After that, the scheduler task updated the next run date to October 5th. However, since the process model was no longer present in the environment, the system attempted to run it 26 times this Sunday, and failed each time, and eventually terminated the instance.
