DDLS487 - Details

• The SAP error message DDLS487 indicates that client annotations are not permitted in abstract entities within the context of the Data Definition Language (DDL) in SAP systems, particularly when working with Core Data Services (CDS) views or similar constructs.
  
  Cause:
  This error typically arises when you attempt to define a CDS view or an entity that is marked as abstract and includes client-specific annotations. In SAP, abstract entities are meant to serve as templates or base entities that cannot be instantiated directly. Client-specific annotations, which are used to manage client-dependent data, are not applicable to abstract entities because they are not meant to hold data directly.
  
  Solution:
  To resolve this error, you should take the following steps:
