• What is the cause and solution for SAP error message PPH_MRP194 - BOM re-explosion required but not supported in MRP Live on HANA ?

  The SAP error message PPH_MRP194 indicates that a Bill of Materials (BOM) re-explosion is required, but it is not supported in the MRP Live functionality on HANA. This error typically arises during the Material Requirements Planning (MRP) process when the system detects that a BOM needs to be re-exploded to accurately calculate requirements, but the MRP Live engine does not support this operation.
  Cause:
  
  BOM Structure Changes: The BOM for the material has been changed, and the MRP Live process requires a re-explosion to reflect these changes in the planning results.
  Multi-Level BOMs: The material may have a multi-level BOM structure that requires re-explosion, which is not supported in the MRP Live environment.
  Configuration Issues: There may be configuration settings in the MRP Live that do not allow for BOM re-explosion.
  Material Master Settings: The material master settings may not be correctly configured to allow for the necessary BOM processing.
  
  Solution:
  
  Switch to Classic MRP: If BOM re-explosion is necessary, consider running the classic MRP (transaction code MD01 or MD02) instead of MRP Live. Classic MRP supports BOM re-explosion.
  Check BOM Configuration: Review the BOM configuration and ensure that it is set up correctly. Make sure that all components are correctly defined and that there are no inconsistencies.
  Material Master Review: Check the material master data for the affected materials to ensure that all relevant fields are correctly filled out and that the material is set up for MRP.
  MRP Live Settings: Review the settings for MRP Live in your system. Ensure that the configuration allows for the necessary planning processes.
  SAP Notes: Check for any relevant SAP Notes or updates that may address this issue. SAP frequently releases notes that provide fixes or enhancements for known issues.
  
  Related Information:
  
  MRP Live vs. Classic MRP: Understand the differences between MRP Live and Classic MRP. MRP Live is optimized for performance and is designed to handle large data volumes, but it has some limitations compared to the classic MRP.
  BOM Management: Familiarize yourself with BOM management in SAP, including how to create, change, and maintain BOMs.
  SAP Documentation: Refer to the official SAP documentation for MRP Live and BOM processing for more detailed information on how to handle BOMs and MRP processes.
  
  If the issue persists after trying the above solutions, it may be beneficial to consult with your SAP support team or reach out to SAP support for further assistance.
