This typically occurs in the context of SAP BW (Business Warehouse) or SAP HANA when you are trying to create or modify a query or data model that involves key figures and characteristics.
  
  Cause:
  The error message "Derivation from data field &1 to key field &2 is not allowed" usually arises due to one of the following reasons:
  
  
  Incompatible Data Types: The data field you are trying to derive from may not be compatible with the key field. For example, if the data field is a text field and the key field is a numeric field, the derivation will fail.
  
  
  Key Field Restrictions: Key fields have specific restrictions on how they can be derived. Certain fields may not allow derivation from other fields due to
