• What is the cause and solution for SAP error message PPH_MRP118 - Number of inserted RESB: &1 (MRP Live on HANA), &2 (classic MRP) ?

  The SAP error message PPH_MRP118 indicates a discrepancy in the number of reservations (RESB) created during the Material Requirements Planning (MRP) process when comparing the results from MRP Live on HANA and the classic MRP. This message typically arises when there is a mismatch in the data processed by the two systems, leading to different numbers of reservations being generated.
  Cause:
  
  Data Inconsistency: There may be inconsistencies in the master data or transaction data that are being used by MRP Live and classic MRP. This can include differences in material master records, BOMs (Bill of Materials), or routing information.
  Configuration Issues: The configuration settings for MRP Live and classic MRP may not be aligned, leading to different processing logic or parameters being applied.
  Execution Context: The execution context (e.g., selection criteria, planning horizon) may differ between the two MRP runs, resulting in different outputs.
  Custom Logic: If there are custom enhancements or user exits that affect the MRP process, they may behave differently in MRP Live compared to classic MRP.
  
  Solution:
  
  Data Validation: Check the material master data, BOMs, and routing information for the materials involved. Ensure that they are consistent and correctly maintained in the system.
  Configuration Review: Review the configuration settings for both MRP Live and classic MRP. Ensure that they are aligned and that any relevant parameters are set correctly.
  Execution Parameters: Compare the selection criteria and planning horizons used in both MRP runs. Ensure that they are the same to avoid discrepancies.
  Log Analysis: Analyze the MRP logs for both processes to identify any specific issues or warnings that may indicate why the results differ.
  SAP Notes: Check for any relevant SAP Notes or updates that may address known issues with MRP Live or classic MRP. Applying these notes may resolve the discrepancy.
  Testing: If changes are made, conduct thorough testing to ensure that the issue is resolved and that both MRP processes yield consistent results.
  
  Related Information:
  
  MRP Live: This is the advanced version of MRP that runs on the HANA database, leveraging its capabilities for faster processing and real-time analytics.
  Classic MRP: This is the traditional MRP process that runs on the standard database and may have different performance characteristics and limitations compared to MRP Live.
  SAP Documentation: Refer to SAP Help documentation for MRP Live and classic MRP for detailed information on configuration and best practices.
  Community Forums: Engage with SAP community forums or support channels for additional insights and shared experiences from other users who may have encountered similar issues.
