ABAP RAP field instance features dump

[#1]

Hello, experts

I have a problem.

I have a management application with some associations. I tried to add behavior for the field which I want to set read-only if other field in this entity is being set to true/false (simple check box) if check box is true then field unrestricted else read-only such a simple requirement.

Behavior for entity you can find below

I implemented corresponding method in behavior pool, every object were activated class and behavior. When I ran application via testing environment, I mean I didn't deploy application just use testing in eclipse I had a short dump that "Handler not implemented; Method: INSTANCE_FEATURE, Involved Entities: ZC_PO_PLANNED_OFFER_PROD_CTP". Short dump is raised once I open entity where I added instance features for the field.

System is S4HANA on Premise version of ABAP platform 2022 SP02

Could somebody explain what I have been doing wrong? 

Thank you in advance for the response

Hi @Kostiantyn_K !

You need to implement the get_instance_features method in your behavior implementation class. Declare it following the example in the screenshot below.

After that, add the implementation for this method.
I hope this helps you.

BR, 
Oleg

Hello,

Thank you for your replay, but what I meant in my post, that I've already implemented method get_instance_features in behavior class, and got short dump, method is not empty it reads data and fill structure %field in result table

[Oleg_Vokh]

Could you please paste the code here behavior class so we can check?
If comment out the logic in a method, will the error remain? Will the debugger work?

@Oleg_Vokh, sure
