The mpp_Operation ItemType is actually a null relationship off of mpp_ProcessPlan. This means that it does not have any related data and also that it has a source_id linking it to an individual Process Plan. Because of this, a single operation cannot be shared between different Process Plans.
Depending on your exact use case, one alternative could be to create a copy of the mpp_Operation that a user selects from the search dialog to attach to your new Process Plan.

Thanks alot for replying me!
Based on my understanding as you said, if I manually add the mpp_Operation Itemtype as a Relationship Type of mpp_ProcessPlan, then would it work that way?
The last question is I try to copy the mpp_Operation as you suggested and it pops up the error as screenshot below, do not have an idea about this. Appreciate it!
