Child Entity Creation without update in RAP

[ankahit]

Hi All,

In managed scenario, How can I ensure that a child entity is only creatable and not editable afterward in RESTful ABAP? When I remove the update capability from the behavior definition, the fields become non-editable even during the creation phase. What is the best approach to achieve this effectively? I also tried field (readonly : update) but it does not work.

Hello,

The answer should be with Behavior Definition only as you tried before.

Try with below Field Characteristics available in Behavior Definition of RAP:

field(readonly:update) Field1

Go through the below documentation:

This should help!

Thanks,

Hi Sijin,

Yes, I tried. But it didn't work. FYI, I have enabled the draft functionality.

What is the problem you are facing when you are using 'field(readonly:update)', Sorry am not able to make out the issue you are facing using the screenshots attached.

We have same Field Characteristics enable for couple of fields but in Root Entity and it works perfectly alright and we also have Draft functionality enabled, so wondering what problem you could be facing.

Thanks,

Sijin

Hi Sijin, for Child entity it does not work. it makes field non editable in create. as well as in update.

Ok, let's wait for some RAP experts comment on this. Ideally my assumption was 'field(readonly:update) Field1' should help in getting this done, irrespective of whether the Entity is Root or Dependent Entities.
