• What is the cause and solution for SAP error message PR034 - Safety stock not calculated as servive level=0 ?

  The SAP error message PR034, which states "Safety stock not calculated as service level = 0," typically occurs in the context of inventory management and planning within SAP. This message indicates that the system is unable to calculate safety stock for a particular material because the service level parameter is set to zero.
  Cause:
  
  
  Service Level Setting: The primary cause of this error is that the service level for the material in question is set to zero. The service level is a critical parameter that defines the desired probability of not running out of stock during the lead time. A service level of zero means that there is no desired level of service, which makes it impossible to calculate safety stock.
  
  
  Master Data Configuration: The material master data or the planning parameters may not be configured correctly. This includes settings in the Material Master (MM) or in the planning strategy.
  
  
  Planning Strategy: The planning strategy assigned to the material may not support safety stock calculations, or it may be incorrectly configured.
  
  
  Solution:
  
  
  Adjust Service Level: 
  
  Navigate to the material master record for the affected material.
  Go to the MRP (Material Requirements Planning) view.
  Check the service level setting and update it to a value greater than zero (e.g., 90% or 95%) based on your business requirements.
  
  
  
  Review Planning Parameters:
  
  Ensure that the planning parameters related to safety stock are correctly set up in the material master.
  Check the safety stock settings in the MRP view and ensure they align with your inventory management strategy.
  
  
  
  Check Planning Strategy:
  
  Review the planning strategy assigned to the material. Ensure that it is appropriate for the type of inventory management you are using (e.g., make-to-stock, make-to-order).
  If necessary, change the planning strategy to one that supports safety stock calculations.
  
  
  
  Recalculate Safety Stock:
  
  After making the necessary adjustments, you may need to run the MRP process again to recalculate the safety stock based on the updated parameters.
  
  
  
  Related Information:
  
  Transaction Codes: You may use transaction codes like MM02 (Change Material) to update the material master or MD02 (MRP Run) to execute the MRP process.
  Documentation: Refer to SAP documentation or help files for detailed guidance on configuring safety stock and service levels.
  Consult with SAP Support: If the issue persists after making the adjustments, consider reaching out to SAP support or your internal SAP team for further assistance.
  
  By addressing the service level setting and ensuring that all related configurations are correct, you should be able to resolve the PR034 error and enable the calculation of safety stock for the affected materials.
