• What is the cause and solution for SAP error message M8_2151 - IR before GR not possible for split valuation with valuated special stock ?

  The SAP error message M8_2151, which states "IR before GR not possible for split valuation with valuated special stock," typically occurs in the context of inventory management and procurement processes. This error is related to the handling of split valuation and special stock types in SAP.
  Cause:
  
  
  Split Valuation: This error arises when you are trying to perform an Invoice Receipt (IR) before a Goods Receipt (GR) for materials that are managed under split valuation. Split valuation allows you to manage different valuations of the same material based on various criteria (e.g., quality, origin, etc.).
  
  
  Special Stock: The error specifically mentions "valuated special stock," which refers to stock that is not owned by the company but is still valued (e.g., consignment stock, project stock, etc.). In this case, the system does not allow an invoice receipt to be processed before the corresponding goods receipt.
  
  
  Configuration Issues: There may be configuration settings in the material master or in the valuation area that are not set up correctly for handling split valuation and special stock.
  
  
  Solution:
  
  
  Perform Goods Receipt First: The primary solution is to ensure that a Goods Receipt (GR) is posted before attempting to post an Invoice Receipt (IR). The GR is necessary to acknowledge the receipt of goods into inventory, which is a prerequisite for processing the invoice.
  
  
  Check Material Master Settings: Review the material master settings for the affected material. Ensure that the split valuation and special stock settings are correctly configured. You can check the valuation type and stock type in the material master record.
  
  
  Review Purchase Order: Ensure that the purchase order is correctly set up to allow for the receipt of goods. Check if the items are set up for split valuation and if the correct valuation types are being used.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on handling split valuation and special stock scenarios.
  
  
  User Authorization: Ensure that the user has the necessary authorizations to perform the GR and IR transactions.
