Job Entry ChangeJobOpDtlCapability BPM Error

I’m trying to create a Method Directive to modify the Capability and Resource of a job when the Op-Standard is modified.

When I modify the Op-Standard I receive an error stating: “Operation Detail is not available”. I created a very similar BPM off of the ChangeJobOpDtlCapability that only changes the resourceID by invoking the ChangeJobOpDtlResourceID method and it works correctly. Am I missing a reference or something that is required because I am writing to a different table?

Thanks,
Adriano
