When attempting to update the object definition for a an Oracle EBS agent, there is no entry in the dropdown for Template Job:
V24, 21
No Template job has been created
Create a template job in either Client 0 or the non-client 0. Once a single OEBS job has been created, this will be available in the agent definition Template Job dropdown.
In the case of Automic SaaS, a template job must be created in the non-zero client (such as client 100)
