• What is the cause and solution for SAP error message SAMDT_VALIDATIONS015 - Derivation having same source and target status variable &1 is invalid ?

  The SAP error message SAMDT_VALIDATIONS015 indicates that there is an issue with the derivation logic in your SAP system, specifically that the source and target status variables are the same, which is not allowed. This typically occurs in the context of data modeling or transformation processes, such as in SAP BW (Business Warehouse) or SAP HANA.
  Cause:
  The error arises when you attempt to create a derivation rule where the source and target variables are identical. This can happen in scenarios where you are trying to derive a value from a variable that is supposed to be transformed or calculated, but instead, you are referencing the same variable for both the source and target.
  Solution:
  To resolve this error, you should:
  
  
  Review the Derivation Logic: Check the derivation rules you have set up. Ensure that the source and target variables are not the same. You need to have a distinct source variable that provides the input for the target variable.
  
  
  Modify the Derivation Rule: If you find that the source and target are indeed the same, you will need to modify the derivation rule. This could involve:
  
  Changing the target variable to a different one that is intended to receive the derived value.
  Adjusting the logic to ensure that the derivation is meaningful and does not reference the same variable.
  
  
  
  Test the Changes: After making the necessary adjustments, test the derivation to ensure that it works as expected and that the error message no longer appears.
  
  
  Consult Documentation: If you are unsure about how to set up the derivation correctly, refer to the SAP documentation or help resources related to the specific module you are working with (e.g., SAP BW, SAP HANA).
  
  
  Related Information:

  Training and Documentation: If you are frequently working with derivations, consider reviewing training materials or documentation on best practices for data modeling and transformation in SAP.
  
  By following these steps, you should be able to resolve the SAMDT_VALIDATIONS015 error and ensure that your derivation logic is correctly implemented.
