RAP - create child with IDENTIFICATION_REFERENCE

lars_kr — Tue, 14 May 2024 10:39:02 GMT

Hello Community,

I have a managed RAP application with 6 child entities. But I can't create the child entities that were specified as Identification_reference only. I can create the child entity specified as Lineitem_reference.

Example:

In this picture you can see that I can create the child in the section “Rollen” with the type #LINEITEM_REFERENCE. This is a 0..* association. Below there is a section “Kommentar” which has the type #IDENTIFICATION_REFERENCE, but is not editable for me. This entity has the association 0..1.

I hope it is not the case that you can only create a child entity via #LINEITEM_REFERENCE.

regards

Lars

Hi Lars,Did you find out how to solve this...

So - to make the best out of this accidental comment - two learnings here:

- one can't delete comments (?)
- pressing shift+enter does not add a newline but posts the comment

😉

Hi Lars, did you find out how to solve this? We have the same problem situation here. For 1:1 cases a solution would be to add the fields of the child entity to the root entity table. Not nice 😕 Best regards Robert

Unfortunately I don't have a solution yet. For a use case like mine with only one field, I solved it with an action. The action opens a pop-up with which I can then fill the field. However, this assumes that there is already a UUID for this child.
