How do we identify Create/Update/Delete actions in RAP application?

[Ram_peddireddi]

Hi Team,

I have a requirement to enable/disable input fields for input based on Create/Update/Delete action and other conditions in RAP application. How do we identify the current action that we are performing (Create/Delete/Update) in the method "get_instance_features". In core ABAP we do have a field TRTYP = H/V for this purpose. How do we do it in RAP model?

Regards,

Ram Peddireddi.

Hi @Ram_peddireddi You may want to try Global / Instance Authorisation that has the Actions user bring to perform.

For more details you may refer below Blog post...

*   Check if EDIT operation is triggered or not 
    IF requested_authorizations-%update = if_abap_behv=>mk-on OR
        requested_authorizations-%action-Edit   = if_abap_behv=>mk-on.
*--> Your code goes here
    ENDIF.

Hope this helps...

Thanks-

Hi Abhishek, How do we identify whether the operation is CREATE or EDIT here?

@Pradeep_Reddy1 

I would select from the base CDS view to check whether the record already exists in the DB. If it does, you can say that current action is an update.

You can try like below 

field ( readonly : update ) fieldname;

Hi Pradeep,

I cannot use features: instance in this case.
