Using BOPF Actions in CDS View

Dear Experts,

Ic have a probelm with implementing the Business Object action in CDS View.

@UI.lineItem: [

-- Standard Lineitem

{ position: 10 },

-- Action Lineitem

{ type: #FOR_ACTION, dataAction: 'BOPF:Copy', label: 'Copy' }

//{ type: #FOR_ACTION, dataAction: 'Z_PSO_BOPF_999:ACTION, label: 'Copy' }

]

As far as I understand under the "dataAction: 'BOPF:Copy'" I should write my Business Object name and actions, defined there.

But it seems it doesn't work. Can someboy give me a hint, how to make it work?

Thank you in advance and best regards

Christian
