So, you've created an ESS Job but you want to set Self-Incompatibility for the same.
By doing this, it will prevent User B from submitting this Job if it's already running as per request submitted by User A.
Let's see how we can achieve this.
- Navigate to the Job definition from Setup and Maintenance
- Edit the custom Job
- Click 'Show more'
- Look for the a field 'Allow multiple pending submissions'
- Set this field value to 'False'
- That's it. We've now set the Self-Incompatibility for this Job
