Pass default values - factory action in RAP
Step 1: Change behavior definition of header interface view.

StuId = stu_id;

}
}

Step 2: Change behavior definition of header consumption view.
projection;
strict ( 2 );
use draft;
define behavior for zcv_ab_hdr_stu13 alias Student
{
use create;
use update;
use delete;
use action Activate;
use action Discard;
use action Edit;
use action Resume;
use action Prepare;
use action CopyStudent;
use action CreateInstance;
use association _attach { create; with draft; }
}
define behavior for zcv_ab_itm_stu13 alias attach
{
use update;
use delete;
use association _Student{ with draft; }
}
* Check and activate.
Step 3: Implement CreateIntsance method.

Step 4: Change the consumption view and add action button.

@Metadata.ignorePropagatedAnnotations: true
define root view entity zcv_ab_hdr_stu13
provider contract transactional_query
as projection on ZIV_AB_HDR_STU13
{
@UI.facet:
[{
id : 'Student',
purpose: #STANDARD,
type: #IDENTIFICATION_REFERENCE,
label: 'Student',
position: 10
},
{
id : 'attach',
purpose: #STANDARD,
type: #LINEITEM_REFERENCE,
label: 'Attachments',
position: 20,
targetElement: '_attach'
}
]
@UI:
{
lineItem: [{ position : 1 , label : 'Student ID' },
{ position: 10 ,

label: 'CopyStudent' },

dataAction: 'CreateInstance',
label: 'CreateInstance' }],
identification: [{ position: 10 , label : 'Student ID' }],
selectionField: [{ position: 10 }]
}
key StuId,
@UI:

identification: [{ position: 20 , label : 'Student Name' }],
selectionField: [{ position: 20 }]
}

}
StuAge,
@UI:

}

}

}

}

}

/* Associations */
_attach : redirected to composition child zcv_ab_itm_stu13
}
* Check and activate.
Step 5: Testing
* Preview the application.
--> StuName,StuAge,StuDob behavior is ON so data is passed.
--> StuCourse,StuCourseDur behavior is OFF, so data is not passed.
--> behavior is not added to StuGender. By default taking as OFF.
