• What is the cause and solution for SAP error message PPH_MRP165 - Optimum lot-sizing procedure not supported by MRP Live on SAP HANA ?

  The SAP error message PPH_MRP165 indicates that the optimum lot-sizing procedure you are trying to use is not supported by MRP Live in SAP HANA. This typically occurs when you are attempting to run a planning run using MRP Live, but the lot-sizing procedure you have configured is not compatible with the MRP Live functionality.
  Cause:
  
  Unsupported Lot-Sizing Procedure: The lot-sizing procedure you are using may not be compatible with MRP Live. MRP Live supports only certain lot-sizing procedures.
  Configuration Issues: There may be configuration issues in the material master or in the MRP settings that lead to this error.
  Version Limitations: The version of SAP you are using may have limitations regarding the lot-sizing procedures supported by MRP Live.
  
  Solution:
  
  
  Check Lot-Sizing Procedure: Review the lot-sizing procedure assigned to the material in the material master (transaction code MM02). Ensure that it is one of the procedures supported by MRP Live. Commonly supported procedures include:
  
  Lot-for-lot (EX)
  Fixed lot size (FX)
  Reorder point (RO)
  Economic order quantity (EOQ)
  
  
  
  Change Lot-Sizing Procedure: If the current lot-sizing procedure is not supported, consider changing it to a supported one. This can be done in the material master under the MRP 2 view.
  
  
  Review MRP Settings: Check the MRP settings in the configuration (transaction code SPRO) to ensure that they are correctly set up for MRP Live.
  
  
  Use Classic MRP: If changing the lot-sizing procedure is not feasible, you may need to run the classic MRP instead of MRP Live. This can be done by using transaction code MD01 or MD02.
  
  
  Consult Documentation: Refer to the SAP documentation or release notes for your specific version to understand the limitations and supported features of MRP Live.
  
  
  SAP Notes: Check for any relevant SAP Notes that may address this issue or provide additional guidance.
  
  
  Related Information:
