  SAP Error Message WR079
  Message Text:
  
  Plant &, material group &: revaluation not affecting margins not allowed
  
  Cause
  This error occurs during the material price revaluation process in SAP (usually in the context of inventory revaluation or price changes). The system is trying to perform a revaluation for a material in a specific plant and material group, but the revaluation does not affect the margins (i.e., the difference between the old and new price is zero or negative in a way that the system does not allow).
  More specifically:
  
  The material price revaluation is set up to only allow changes that affect the profit margins.
  The system detects that the revaluation would not impact the margins (e.g., the new price is equal to or less than the old price in a scenario where margin-affecting revaluation is mandatory).
  This is often controlled by configuration settings or business rules that prevent revaluation entries that do not affect margins, to avoid unnecessary accounting entries or incorrect margin reporting.
  
  
  When Does This Happen?
  
  During price revaluation runs (transaction MR21, or mass revaluation via MR22, or during period-end closing activities).
  When the system checks the impact of the revaluation on the margin and finds no effect.
  When the material is assigned to a material group and plant combination that is configured to disallow non-margin affecting revaluations.
  
  
  Solution
  
  
  Check the Revaluation Parameters:
  
  Review the revaluation settings in the system (e.g., in the valuation area, price control, and revaluation profile).
  Verify if the system is set to allow only margin-affecting revaluations.
  This can be controlled in configuration or via user exit/custom logic.
  
  
  
  Review the Price Differences:
  
  Check the old and new prices for the material in the specified plant and material group.
  Confirm if the price difference is zero or negative in a way that violates margin rules.
  
  
  
  Adjust the Revaluation Strategy:
  
  If the business allows revaluation even if margins are not affected, adjust the configuration to permit such revaluations.
  This might involve changing settings in Material Ledger or Price Control.
  
  
  
  Consult with Finance/Controlling:
  
  Since this relates to margin impact, coordinate with finance or controlling teams to understand if the revaluation should be allowed.
  They may provide guidance on whether to allow non-margin affecting revaluations or not.
  
  
  
  Technical Checks:
  
  Check if any user exits or BAdIs are implemented that restrict revaluation based on margin impact.
  Review custom code or enhancements that might trigger this error.
