• What is the cause and solution for SAP error message MD802 - Use a suitable lot-sizing procedure ?

  The SAP error message MD802, which states "Use a suitable lot-sizing procedure," typically occurs in the context of Material Requirements Planning (MRP) when the system is unable to determine a suitable lot-sizing procedure for a material. This can happen during the planning run when the system is trying to calculate the quantities to be produced or procured based on the demand and supply situation.
  Cause:
  
  Missing Lot Sizing Procedure: The material master record does not have a defined lot-sizing procedure.
  Incorrect Configuration: The lot-sizing procedure defined in the material master may not be appropriate for the planning scenario.
  MRP Type Issues: The MRP type assigned to the material may not support the lot-sizing procedure being used.
  Planning Parameters: The planning parameters set in the MRP configuration may not align with the requirements for the material.
  
  Solution:
  
  
  Check Material Master:
  
  Go to the material master record (transaction code MM03).
  Check the MRP 1 view for the lot-sizing procedure field. Ensure that a suitable lot-sizing procedure is assigned (e.g., 'EX' for lot-for-lot, 'HB' for fixed lot size, etc.).
  
  
  
  Review Lot Sizing Procedures:
  
  Ensure that the lot-sizing procedure is appropriate for the material and its usage. You can refer to the SAP documentation for the different lot-sizing procedures available.
  
  
  
  MRP Type Verification:
  
  Check the MRP type assigned to the material. Ensure that it is compatible with the lot-sizing procedure. For example, if the MRP type is 'PD' (for MRP), it should support the lot-sizing procedure you are trying to use.
  
  
  
  Check Planning Parameters:
  
  Review the planning parameters in the MRP configuration (transaction code OMD0) to ensure they are set correctly for the materials being planned.
  
  
  
  Customizing Settings:
  
  If necessary, adjust the customizing settings for lot-sizing procedures in the SAP system. This can be done in the SPRO transaction under the MRP settings.
  
  
  
  Consult Documentation:
  
  Refer to SAP Help documentation or consult with your SAP functional consultant for specific guidance on the lot-sizing procedures and their implications.
