Smart SAP Assistant

• What is the cause and solution for SAP error message CFD_REGISTRY_CHECK351 - CDS View &1 is no RAP BO view (i.e. used in BDEF) ?

  The SAP error message CFD_REGISTRY_CHECK351 indicates that a Core Data Services (CDS) view is not recognized as a RAP (Rapid Application Programming) Business Object (BO) view. This error typically arises when you are trying to use a CDS view in a Business Definition (BDEF) that is not properly defined as a RAP BO.
  Cause:
  
  Incorrect CDS View Definition: The CDS view you are trying to use is not defined as a RAP Business Object. This means it does not have the necessary annotations or structure to be recognized as a RAP BO.
  Missing Annotations: The required annotations for RAP BOs, such as @ObjectModel: { ... }, may be missing from the CDS view.
  Incompatible View Type: The CDS view might be of a type that is not compatible with RAP, such as a view that does not support transactional operations.
  
  Solution:
  
  
  Check Annotations: Ensure that the CDS view has the appropriate annotations for RAP. You should include the @ObjectModel annotation to define it as a business object. For example:
  @AbapCatalog.sqlViewName: 'Z_MY_CDS_VIEW'
  @AbapCatalog.compiler.compareFilter: true
  @ObjectModel: { ... }  // Add necessary RAP annotations here
  define view Z_MY_CDS_VIEW as select from ...
  
  
  Define as RAP BO: If the CDS view is intended to be a RAP BO, make sure it is defined correctly in the Business Definition (BDEF) and that it adheres to the RAP guidelines.
  
  
  Review the Business Definition: Check the Business Definition (BDEF) where the CDS view is being used. Ensure that the view is correctly referenced and that it meets the requirements for being a RAP BO.
  
  
  Use Compatible Views: If the CDS view is not meant to be a RAP BO, consider using a different view that is compatible with RAP or redesign the existing view to meet the RAP requirements.
  
  
  Related Information:
  
  RAP Documentation: Refer to the official SAP documentation on RAP to understand the requirements and best practices for defining RAP Business Objects and their associated CDS views.
  SAP Notes: Check for any relevant SAP Notes that might address specific issues or provide updates related to RAP and CDS views.
  Community Forums: Engage with the SAP community forums or SAP Help Portal for additional insights and solutions from other developers who may have encountered similar issues.
