• What is the cause and solution for SAP error message WRF_APC044 - Enter a valid hierarchy; hierarchy &1 is not active ?

  The SAP error message:
  WRF_APC044 Enter a valid hierarchy; hierarchy &1 is not active
  typically occurs in the context of SAP Advanced Planning and Optimization (APO), specifically within the Demand Planning or Supply Network Planning modules where hierarchies (such as product or location hierarchies) are used.
  
  Cause
  
  The hierarchy you are trying to use or reference in the planning process is not active in the system.
  In SAP APO, hierarchies must be activated before they can be used in planning or reporting.
  The hierarchy might be created but not yet activated, or it might have been deactivated.
  This can happen if:
  
  The hierarchy was recently created or changed but not activated.
  The hierarchy was deactivated intentionally or due to a system issue.
  The user is referencing an incorrect or outdated hierarchy ID.
  
  
  
  
  Solution
  
  
  Check the Hierarchy Status:
  
  Go to the transaction or application where hierarchies are maintained (e.g., in SAP APO, use transaction /SAPAPO/SDP94 or the relevant planning book or master data maintenance screen).
  Verify the status of the hierarchy &1 (the placeholder in the message will be replaced by the actual hierarchy ID).
  
  
  
  Activate the Hierarchy:
  
  If the hierarchy is inactive, activate it.
  In SAP APO, hierarchies are activated via the hierarchy maintenance screen:
  
  Open the hierarchy.
  Use the "Activate" function (usually a button or menu option).
  
  
  Save the changes.
  
  
  
  Verify the Hierarchy ID:
  
  Ensure that the hierarchy ID you are entering is correct and exists in the system.
  If you are entering it manually, check for typos.
  
  
  
  Check Authorizations:
  
  Ensure you have the necessary authorizations to view and activate hierarchies.
  
  
  
  Transport and System Consistency:
  
  If the hierarchy was transported from another system, verify that the transport was successful and the hierarchy is active in the target system.
