  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 was recently created or changed but not activated.

  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
