• What is the cause and solution for SAP error message SD_CDS_ENTITY065 - Child Entity must be a CDS View, abstract entity or custom entity ?

  The SAP error message SD_CDS_ENTITY065 indicates that there is an issue with the definition of a child entity in a Core Data Services (CDS) view. Specifically, the error states that the child entity must be a CDS view, an abstract entity, or a custom entity. This typically occurs when you are trying to define a relationship in a CDS view, but the entity you are referencing does not meet the required criteria.
  Cause
  The error can occur due to several reasons:
  
  Incorrect Entity Type: The child entity you are trying to reference is not a valid CDS view, abstract entity, or custom entity.
  Misconfiguration: There may be a misconfiguration in the CDS view definition, such as incorrect annotations or missing definitions.
  Dependency Issues: The child entity might depend on another entity that is not properly defined or activated.
  
  Solution
  To resolve the error, you can take the following steps:
  
  
  Check Entity Definition:
  
  Ensure that the child entity you are referencing is indeed a CDS view, abstract entity, or a custom entity. You can do this by checking the definition in the ABAP Development Tools (ADT) or the relevant transaction codes in SAP.
  
  
  
  Review Annotations:
  
  Verify that the annotations in your CDS view are correctly defined. Ensure that you are using the correct syntax and that all required annotations are present.
  
  
  
  Activate Entities:
  
  Make sure that all entities involved (both parent and child) are activated. Inactive entities can lead to errors when trying to reference them.
  
  
  
  Check for Dependencies:
  
  If the child entity depends on other entities, ensure that those entities are also correctly defined and activated.
  
  
  
  Use the Right Context:
  
  Ensure that you are using the correct context for the child entity. If you are working within a specific namespace or package, make sure that the child entity is accessible from that context.
  
  
  
  Consult Documentation:
  
  Refer to the SAP documentation for Core Data Services to ensure that you are following best practices and guidelines for defining entities and relationships.
