• What is the cause and solution for SAP error message SAMDT_VALIDATIONS018 - Derivation from &1 &2 is invalid,derivative &3 has outbound derivation ?

  The SAP error message SAMDT_VALIDATIONS018 indicates that there is an issue with the derivation of a certain value in the context of SAP's data management or master data governance processes. Specifically, the message states that the derivation from the specified source (indicated by &1 and &2) is invalid because the derivative (indicated by &3) has an outbound derivation.
  Cause:
  
  Invalid Derivation Logic: The derivation logic defined in the system may not be correctly set up, leading to an invalid relationship between the source and the derivative.
  Outbound Derivation Conflict: The derivative may have an outbound derivation that conflicts with the current derivation attempt. This means that the system is trying to derive a value that is already being derived from another source, which is not allowed.
  Configuration Issues: There may be configuration issues in the master data governance or data management settings that are causing the derivation to fail.
  
  Solution:
  
  Review Derivation Rules: Check the derivation rules defined in the system for the specific data objects involved. Ensure that the rules are correctly set up and do not conflict with each other.
  Check Outbound Derivations: Investigate the outbound derivation for the derivative indicated by &3. Ensure that it is not conflicting with the current derivation attempt. You may need to adjust the outbound derivation or the current derivation logic.
  Adjust Configuration: If there are configuration issues, you may need to adjust the settings in the relevant SAP modules (like SAP Master Data Governance) to ensure that the derivation logic is valid.
  Consult Documentation: Refer to SAP documentation or help resources for guidance on how to set up derivations correctly and troubleshoot common issues.
  Testing: After making changes, test the derivation process to ensure that it works as expected without generating errors.
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may address this specific error message or provide additional guidance on derivation issues.
  SAP Community: Engage with the SAP Community forums to see if other users have encountered similar issues and what solutions they have found.
  Transaction Codes: Familiarize yourself with relevant transaction codes (like MDGIMG for Master Data Governance) that can help you navigate to the configuration settings related to derivations.
  
  If the issue persists after following these steps, it may be beneficial to consult with an SAP expert or your organization's SAP support team for further assistance.
