• What is the cause and solution for SAP error message CDSCORE008 - Attribute &1 already exists ?

  The SAP error message CDSCORE008 indicates that there is an attempt to define an attribute in a Core Data Services (CDS) view that already exists. This typically occurs when you are trying to create a CDS view and you have defined an attribute with the same name as an existing attribute in the same context.
  Cause:
  
  Duplicate Attribute Definition: The most common cause is that the attribute name you are trying to use is already defined in the same CDS view or inherited from a parent view.
  Inconsistent Naming: If you are using a naming convention that leads to similar names being generated, it can cause conflicts.
  Inclusion of Multiple Data Sources: If you are joining multiple tables or views, there may be overlapping attribute names.
  
  Solution:
  
  Rename the Attribute: Change the name of the attribute you are trying to define to something unique that does not conflict with existing attributes.
  Check for Inherited Attributes: If you are extending a base view, check the attributes defined in the base view to ensure you are not duplicating names.
  Review Joins and Associations: If your CDS view includes joins or associations, ensure that the attributes from the joined tables do not have the same name as those in your main view.
  Use Aliases: If you need to include an attribute from a joined table that has the same name as an existing attribute, consider using an alias to differentiate them.
