SAP Cloud SDK : Radio-button Issue in Embed Component

Hi Experts,

We have created embed component from XBO and structure are as below.

import AP.Common.GDT;

import AP.Common.Global;

import AP.CRM.Global;

[Extension] businessobject AP.CRM.Global:CustomerQuote {

   element zfile_type : ZZPTypeCode;

   element zfext_ile : ID;

   element znew_file: ID;

   element zexp_date : Date;

   action ZnSubmit;

   action ZOVSChange;

   node Item {

      }

   node ItemProposal {

       }

}

Now ZZPTypeCode is created as Code List Data Type and using this all fields we have created embed component and add into overview screen.

I have created radiobutton and binding with this zfile(ZZPTypeCode) field and radiobutton display with text given into Code List Data Type.

When user open any order screen i can able to see that embed component into overview screen. Once user select 1 radiobutton (R1) and click on save it it store into database and i have check in Repository Explorer and run QueryByElement from CustomerQuote i can able to see custom field into Result.

Issue 1:

When I again open same order i can not see saved record or radio button selected and all blank without selected.

Issue 2:

I have also make if default value in BO definition as below syntax

element zfile_type : ZZPTypeCode = ZZPTypeCode.CO_R1;

but it is not selected by default sometime it works and sometime not.

Please anyone have idea help me.

Regards,

Mithun
