• What is the cause and solution for SAP error message WXP363 - Planning step &1/&2 cannot be used for derivating ?

  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  WXP363 Planning step &1/&2 cannot be used for derivating
  
  Meaning / Cause:
  This error occurs during the production planning or order processing when the system tries to derive or copy data from one planning step to another, but the specified planning step combination (&1 = planning group, &2 = planning step) is not allowed or not configured for derivation.
  In SAP PP (Production Planning), planning steps represent different stages or statuses in the production process (e.g., planned order, firmed order, released order). Derivation means copying or transferring data from one planning step to another, often used in order conversion or order processing.
  The error indicates that the system cannot perform derivation because the planning step combination is either:
  
  Not defined in the system for derivation, or  
  The planning step is not allowed to be used as a source or target in derivation, or  
  The customizing settings for planning steps and their derivation rules are missing or incorrect.
  
  
  Where it occurs:
  
  During order processing (e.g., converting planned orders to production orders)  
  When using planning step derivation in production order management  
  In the configuration of planning steps and their derivation rules
  
  
  Solution / How to fix:
  
  
  Check Customizing for Planning Steps:
  
  Go to transaction OPPR (or via IMG path:
  
  Production ? Shop Floor Control ? Master Data ? Define Planning Steps)  
  Verify that the planning steps &1 and &2 exist and are correctly defined.
  
  
  
  Check Derivation Settings:
  
  In the IMG, navigate to:
  
  Production ? Shop Floor Control ? Master Data ? Define Planning Step Derivation  
  Ensure that the derivation from planning step &1 to &2 is allowed and properly maintained.
  
  
  
  Maintain Planning Step Derivation Rules:
  
  If the derivation rule is missing, create or adjust it to allow derivation between the specified planning steps.
  
  
  
  Check User Exits or Enhancements:
  
  If custom logic is implemented for planning step derivation, verify that it does not block or incorrectly handle the derivation.
  
  
  
  Check Authorizations:
  
  Ensure the user has the necessary authorizations to perform the derivation or order processing steps.
  
  
  
  Testing:
  
  After adjustments, test the order processing or planning step derivation again to confirm the error is resolved.
  
  
  
  
  Additional Information:
  
  Planning steps are used to control the status and processing of production orders and planned orders.  
  Proper configuration of planning steps and their derivation is essential for smooth order processing.  
  This error is a warning (WXP) type message, indicating a configuration or process issue rather than a system failure.
  
  
  If you provide the exact planning steps &1 and &2 values, I can help you with more specific guidance.
  
  Summary:
  
  The error "WXP363 Planning step &1/&2 cannot be used for derivating" means the system cannot derive data between the specified planning steps due to missing or incorrect configuration. The solution is to check and maintain the planning step definitions and derivation rules in customizing (transaction OPPR and related IMG settings).
  
  If you need, I can also provide the IMG path screenshots or detailed steps for customizing.
