• What is the cause and solution for SAP error message SDDL_PARSER_MSG426 - Virtual element name "&1" overlaps with the name of the basis entity ?

  The SAP error message SDDL_PARSER_MSG426 indicates that there is a conflict between a virtual element name and the name of a basis entity in your SAP system. This typically occurs in the context of SAP Data Dictionary or when working with Core Data Services (CDS) views, where virtual elements are defined.
  Cause:
  The error arises when:
  
  A virtual element (which is usually a calculated field or derived attribute) is defined with the same name as an existing basis entity (like a table or a field in a table).
  This naming conflict prevents the system from correctly interpreting the virtual element, as it cannot distinguish between the two.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Rename the Virtual Element: 
  
  Change the name of the virtual element to something unique that does not conflict with any existing basis entity names. Ensure that the new name is descriptive and follows your organization's naming conventions.
  
  
  
  Check for Naming Conventions:
  
  Review your naming conventions for virtual elements and basis entities to avoid future conflicts. It’s a good practice to use prefixes or suffixes for virtual elements to distinguish them from standard fields.
  
  
  
  Review the Data Model:
  
  If the virtual element is part of a CDS view or a similar construct, review the entire data model to ensure that there are no other naming conflicts.
  
  
  
  Test the Changes:
  
  After renaming the virtual element, activate the changes and test the functionality to ensure that the error is resolved and that the virtual element behaves as expected.
