• What is the cause and solution for SAP error message 1R020 - &1 is not permitted as a derived category since it is a logical category ?

  The SAP error message "1R020 &1 is not permitted as a derived category since it is a logical category" typically occurs in the context of SAP Business Warehouse (BW) or SAP Analytics when dealing with the categorization of data or objects. This error indicates that you are trying to use a logical category as a derived category, which is not allowed.
  Cause:
  
  Logical Category: The category you are trying to use is defined as a logical category. Logical categories are typically used for grouping or classifying data in a way that does not allow for further derivation.
  Derived Category Misuse: You may be attempting to create a derived category based on a logical category, which is not permitted in SAP BW or similar systems.
  
  Solution:
  
  Check Category Definitions: Review the definitions of the categories you are working with. Ensure that you are not trying to derive a new category from a logical category.
  Use Appropriate Categories: If you need to create a derived category, ensure that you are using a non-logical category as the base. You may need to create a new category that is not defined as logical.
  Modify Data Model: If necessary, adjust your data model to ensure that the relationships between categories are correctly defined and that logical categories are not being misused in derivations.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on category definitions and their permissible uses.
