RAP: Modify column values in Object page items table via custom action

[Mepspa]

Hello,

I need to mass modify column values on Object Page table items with values inserted from a  Dialog:

After pushing the Apply button, the new date will be updated in the items tables for the selected rows.

What I did:

- to insert the button at the toolbar level, I used BAS Page Map. Manifest.json has been modified accordingly:

In the controller generated, I implemented the logic to open the dialog:

the problems arise in the logic to handle the OK button. I need to get the selected rows and to pass them to the RAP custom action logic:

How can I get the currently selected Items in the Object Page table and how to pass these as parameters to the RAP object ?

Many thanks

Filippo

Any reason why you haven't defined this function in RAP BO? Defining this function in RAP BO would make your life much simpler.

I think the way is going through side effects. I found an example here  but it's on CAP not RAP. So we need to translate the Service cds document into behavior definition.
