The Lookup.USR_PROCESS_TRIGGERS is not working. Assigned some process task on user attribute changes but it is not working as of now. Earlier it was working fine. Even I am not able to update the existing lookup value in Lookup.USR_PROCESS_TRIGGERS as we are getting below errror:
The security level for this data item indicates that it cannot be updated.
We are not able to figure out what is the issue behind this. might be some sandbox issue or some database value problem.
