How to transfer selected items from List Page to popup Abstract Entity in RAP?

[Andrei_Karanchuck]

I have an application where, on the List Page, I select multiple records, and then click a button to process them. I need to choose the main item from the selected records, and for that, a popup created through Abstract Entity appears. In this popup, I need to pass the selected data from the List Page into a dropdown.

Example workflow

1. I select several record  

2. I click a button that opens the Abstract Entity dialog 

3. In this dialog, I need to choose from the previously selected items 

Here is your Abstract Entity code :

@EndUserText.label: 'Abstract Entity'
@Metadata.allowExtensions: true
define root abstract entity ZCPO_ProdOrder_ENTITY

{
  @EndUserText.label: 'Choice reference production order'
  key productionOrder : abap.char(12);
}

How can this functionality be implemented?

Thanks and Regards, 
Andrei

Hi @Andrei_Karanchuck  you may use annotations as below, Assuming you are already reading the record based on Key selected from table  record...

This should go in your Abstract Entity 

@UI.defaultValue: #( 'ELEMENT_OF_REFERENCED_ENTITY: <Column_Name>' )
status : abap_boolean;

 You may add as many columns you want to add in Abstract Entity popup. Please refer below post for more details:

Hope this helps...

I wrote the following blog post, which demonstrates how to pass multiple selected items to an action that accepts deep (table) parameters. This does not use a popup but instead triggers the action in a controller extension:
