• What is the cause and solution for SAP error message CFD_DE_UTILITIES011 - Invalid extension. MDS implemented Entites must not have CDS Extensions. ?

  The SAP error message CFD_DE_UTILITIES011 Invalid extension. MDS implemented Entities must not have CDS Extensions typically occurs in the context of Core Data Services (CDS) views and the Model Driven Services (MDS) framework in SAP. This error indicates that there is an attempt to extend a CDS view that is already implemented as an MDS entity, which is not allowed.
  Cause:
  
  MDS Implementation: The entity in question is implemented using MDS, which means it is designed to be a standalone entity without extensions.
  CDS Extension Attempt: There is an attempt to create a CDS extension for this MDS entity, which violates the rules of MDS. MDS entities are not meant to be extended using CDS views.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Entity Definition: Verify if the entity you are trying to extend is indeed an MDS entity. You can do this by checking the definition in the relevant SAP system or documentation.
  
  
  Avoid Extensions: If the entity is an MDS entity, you should avoid creating a CDS extension for it. Instead, consider using the existing entity as is or look for alternative ways to achieve your requirements without extending the MDS entity.
  
  
  Create a New CDS View: If you need additional fields or logic, consider creating a new CDS view that references the MDS entity instead of extending it. This way, you can build upon the existing data model without violating the MDS rules.
  
  
  Consult Documentation: Review the SAP documentation related to MDS and CDS to understand the limitations and best practices for working with these technologies.
