• What is the cause and solution for SAP error message RAP_CMP_CHECKS083 - Property &1 of entity type &2 set to read only. ?

  The SAP error message RAP_CMP_CHECKS083 indicates that a property of an entity type is set to read-only, and an attempt was made to modify it. This error typically occurs in the context of the SAP RAP (Rapid Application Programming) model, which is used for developing business applications in SAP S/4HANA.
  Cause:
  The error occurs when:
  
  You are trying to update or modify a property that is defined as read-only in the entity type.
  The property may be a calculated field or a field that is not intended to be changed directly by the user or application logic.
  
  Solution:
  To resolve this error, consider the following steps:
  
  
  Check Entity Definition: Review the definition of the entity type in your RAP model. Ensure that the property you are trying to modify is not defined as read-only. You can do this by checking the annotations in the CDS (Core Data Services) view or the behavior definition.
  
  
  Modify the Logic: If the property is indeed read-only, you need to adjust your application logic to avoid attempting to modify it. Instead, focus on updating other properties that are writable.
  
  
  Review Business Logic: If the property should be writable based on your business requirements, you may need to change its definition in the CDS view or behavior definition to allow updates. This may involve:
  
  Changing the property from read-only to writable.
  Ensuring that the necessary logic is in place to handle updates correctly.
  
  
  
  Consult Documentation: Refer to the SAP documentation for RAP and the specific entity type you are working with. This can provide insights into the intended use of the property and any constraints that may apply.
  
  
  Testing: After making changes, thoroughly test the application to ensure that the error is resolved and that the application behaves as expected.
  
  
  Related Information:
  
  RAP Model: The RAP model is designed to simplify the development of business applications by providing a clear separation of concerns between the data model and the business logic.
  CDS Views: Core Data Services (CDS) views are used to define the data model in SAP. They can include annotations that specify whether a property is read-only or writable.
  Behavior Definition: In RAP, behavior definitions specify how entities can be manipulated (e.g., create, read, update, delete). Ensure that the behavior definition aligns with your intended use of the properties.
