RAP - Error on validation message highlight

[rodrigo_oliveira5]

Hello,

I have a validation running on save for Child entity, which is a list item within my object page, and I'm unable to properly highlight a field as you can see on the following print - the row is marked as unknown.

Shouldn't the following set of parameters be enough to provide a non-state message with a highlight? I'm also feeding %tky to failed-child.

reported-child=
  VALUE #(
    BASE reported-child(
      %tky = ls_child-%tky
      %path = VALUE #(
        root-%is_draft = ls_child-%is_draft
        root-%key-RootUUID = ls_child-RootUUID
      )
      %msg = new_message(
        id       = 'ZTEST_MSG'
        number   = '018'
        severity = if_abap_behv_message=>severity-error
      )
      %element-%field-allocatedquantity = if_abap_behv=>mk-on
      "%state_area = 'qty_not_null'
      "%element-%assoc-_root = if_abap_behv=>mk-on
    )
).

                }
            }
        }
    }
}

I've refrained from using state messages because of a seemingly known issue, mentioned in a guide (https://github.com/SAP-archive/teched2020-DEV260/tree/main/exercises/ex9). Unfortunately, I couldn't find any information on which versions first presented the issue or which version solves it. Uncommenting %state_area on the excerpt above causes me the same error that is shown on the next print.

I'm currently on an on-prem system running 2021 FPS2.

Please, am I missing anything?

Best regards,

Rodrigo.

Hi rodrigo,

I had the same problem and I found the solution for this problem during debugging in Frontend.

You need to add %is_draft = '01' in your reported-child structure, because the UI is filtering on IsActiveEntity=true in the Object Page Table as you are still in draft mode when filling failed.

Cheers
