• What is the cause and solution for SAP error message WXPA016 - Plan version &1 is not assigned to scenario &2 / step &3 ?

  The SAP error message:
  WXPA016 Plan version &1 is not assigned to scenario &2 / step &3
  typically occurs in the context of SAP Product Lifecycle Costing (PLC) or Product Cost Planning when working with planning versions, scenarios, and steps.
  
  Cause
  This error means that the plan version you are trying to use or reference is not assigned to the specified scenario and step in the system. In SAP, plan versions are linked to specific scenarios and steps to control and organize different planning data sets. If the plan version is not properly assigned, the system cannot find the relevant data for the scenario/step combination you are working with.
  
  Explanation of the placeholders:
  
  &1 = Plan version (e.g., 0001)
  &2 = Scenario (e.g., 01)
  &3 = Step (e.g., 0001)
  
  
  When does this happen?
  
  When you try to execute costing or planning functions that require a plan version linked to a scenario and step.
  When you try to display or change data for a plan version that has not been assigned to the scenario/step.
  During data transfer or simulation runs in PLC or Product Cost Planning.
  
  
  Solution
  
  
  Assign the Plan Version to the Scenario and Step:
  
  Use transaction CKMSTART or CKM3 (depending on your SAP version and module) to check plan versions.
  Go to the configuration or master data maintenance for plan versions.
  Assign the plan version to the required scenario and step.
  
  
  
  Check the Configuration:
  
  In customizing (SPRO), navigate to:
  Controlling -> Product Cost Controlling -> Product Cost Planning -> Version Management -> Define Plan Versions
  
  Ensure that the plan version is assigned to the correct scenario and step.
  
  
  
  Use Transaction CKM3 or CKMSTART:
  
  Verify if the plan version exists and is assigned.
  If not, create or assign it accordingly.
  
  
  
  Check User Input:
  
  Verify that the correct plan version, scenario, and step are entered in the transaction or report.
  Sometimes a typo or wrong input causes the system to look for a non-assigned plan version.
  
  
  
  Transport or Copy Plan Versions:
  
  If you are working in a development or test system, ensure that plan versions and their assignments have been transported correctly.
  
  
  
  
  Additional Information
  
  Plan Versions are used to manage different sets of planning data, e.g., current plan, target plan, simulation plan.
  Scenarios and Steps allow you to organize and differentiate planning data within a plan version.
  Proper assignment is crucial for costing runs, simulations, and reporting.
  This error is common when setting up new plan versions or when migrating data between systems.
