Set field Read only in Restful Application Programming when creating record

[AbhishekSharma]

Hi Gurus,

I am trying to set Additional Binding fields to be readonly in RAP while creating record...

When I run application the field still allows to change the value.

When I choose value from F4 short description gets updated but the field is still editable. How can I make it readonly...

Below is annotation :

@UI:{ lineItem: [ { position : 80 } ],
     identification : [{ position : 80 }] }
     @Consumption.valueHelpDefinition: [{ entity:
  {name: 'ZI_GENDER_5001' , element: 'Value' },
  distinctValues: true,
  additionalBinding: [{ localElement: 'Genderdesc', 
                        localParameter: '',
                        localConstant: '',
                        parameter: '',
                        element: 'Description',
                        usage: #FILTER_AND_RESULT }]
  }]
  Gender;
  @UI: { //lineItem:       [{ position: 100, importance: #HIGH, label: '' }],
    identification: [{ position: 100, label: '', importance: #HIGH }] }
  
  Genderdesc;
  @UI:{ lineItem: [ { position : 90 } ],
     identification : [{ position : 90 }] }

I have tried @ObjectModel.readonly = true

but getting error message property is not released yet.

Please help...

See "readonly" in CDS BDL - field characteristics.

[Edrilan_Berisha · Accepted solution]

in RAP you do not use the annotation anymore on CDS view level or projection level.

You have to define this in the behavior definition.

the syntax is the following:

field ( readonly ) Genderdesc;

You should synchronize your RAP BO afterwards again and depending on if you still have a gateway service in place or not, you should also regenerate that.

Hello Edrilan, I had recently a similar requirement to the one in this blog (to make a custom field read only in the standard Sales Order V2 Fiori tile) and it worked by extending the standard Behavior definition with the "field ( read only ) YY1_..." statement. I have a question though. What if, my custom field needs to be made read only based on a specific rule and made available based on another rule? In this case the "field ( read only ) ..." won't work anymore. Do you know how to implement such requirement ? (I would like to avoid adding a logic to check if the field is maintained or not, at the SAVE operation or at a BAdI SAVE operation). Thank you
