B2B WO Title from Maintenance Work Requirement

Summary:

B2B WO Title from Maintenance Work Requirement

Content (required):

B2B work orders are getting generated through ESS Job 'Create Service Work Orders for Preventive Maintenance' where the B2B WO Title comes from Work Definition Name from Maintenance Cloud which is a standard behavior. However, we have a requirement to pick the Maintenance Work Requirement name instead of Work Definition in B2B Title field. We have tried to achieve this through the trigger in B2B WO object but it doesn't work with the ESS job. It works when we manually update B2B WO from UI but not work with work order created through ESS job. Any idea/suggestion will be grateful.
