• What is the cause and solution for SAP error message RAP_CMP_CHECKS012 - Alias &1 removed for CDS view &2 of service definition &3. ?

  The SAP error message RAP_CMP_CHECKS012 indicates that an alias has been removed for a Core Data Services (CDS) view associated with a service definition in the context of the RAP (Rapid Application Programming) model. This error typically arises during the activation or usage of a service definition in the SAP Business Technology Platform (BTP) or when working with the RAP framework.
  Cause:
  The error can occur due to several reasons:
  
  Alias Removal: The alias specified in the CDS view has been removed or is no longer valid. This can happen if the underlying CDS view has been modified or if the alias was explicitly deleted.
  Inconsistent Metadata: There may be inconsistencies in the metadata of the CDS view or the service definition, leading to the inability to resolve the alias.
  Changes in Data Model: If there have been changes in the data model that affect the CDS view or its aliases, this can lead to the error.
  Transport Issues: If the CDS view or its associated objects were transported between systems and the transport did not include all necessary components, this could lead to missing aliases.
  
  Solution:
  To resolve the error, you can take the following steps:
  
  
  Check the CDS View: 
  
  Open the CDS view in the ABAP Development Tools (ADT) or SE11 transaction and verify that the alias is correctly defined.
  Ensure that the alias is still valid and has not been removed or renamed.
  
  
  
  Review Service Definition:
  
  Check the service definition associated with the CDS view. Ensure that it references the correct CDS view and that all aliases are correctly defined.
  
  
  
  Re-activate the CDS View:
  
  Sometimes, simply reactivating the CDS view can resolve issues related to metadata inconsistencies. Right-click on the CDS view in ADT and select "Activate".
  
  
  
  Check for Transport Issues:
  
  If the issue arose after a transport, ensure that all related objects (including the CDS view and its aliases) were included in the transport request.
  
  
  
  Debugging:
  
  If the issue persists, consider debugging the service definition to identify where the alias is being referenced and why it is not being resolved.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or notes related to RAP and CDS views for any specific guidance or known issues.
