Why do we set Capabilities, Resource Grps, and ID’s at the Operation Code Level and then also set them at the Operation Scheduling Detail Level on the MOM?

I assume in a status of conflict the more granular MOM Operation Scheduling Detail Level would take precedence?

You don’t have to build your MOMs by Operation. You can use Capabilities and Resource Groups to build out the MOM.
