• What is the cause and solution for SAP error message PPH_MRP407 - Number of materials selected for planning: &1 ?

  The SAP error message PPH_MRP407 indicates that the number of materials selected for planning exceeds the maximum limit set in the system. This can occur during the Material Requirements Planning (MRP) process when the system attempts to plan a large number of materials simultaneously.
  Cause:
  
  Exceeding Limits: The system has a predefined limit for the number of materials that can be processed in a single planning run. If the number of materials exceeds this limit, the error will be triggered.
  Configuration Settings: The limit may be configured in the system settings, and it might be set too low for the volume of materials you are trying to plan.
  Selection Criteria: The selection criteria used for the planning run may inadvertently include too many materials.
  
  Solution:
  
  
  Adjust Selection Criteria: Review and modify the selection criteria for the planning run to reduce the number of materials being processed at one time. This can be done by filtering based on specific criteria such as material type, plant, or other relevant parameters.
  
  
  Batch Processing: If you have a large number of materials to plan, consider breaking them into smaller batches and running the MRP process multiple times for each batch.
  
  
  Configuration Changes: If necessary, consult with your SAP Basis or configuration team to review and potentially increase the limit for the number of materials that can be selected for planning. This may involve changes in the configuration settings related to MRP.
  
  
  Check for Updates: Ensure that your SAP system is up to date with the latest patches and updates, as there may be improvements or changes in newer versions that address this issue.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on MRP settings and limits.
  
  
  Related Information:
  
  Transaction Codes: You may use transaction codes like MD01 (MRP Run) or MD02 (Single-item, Multi-level MRP) to initiate planning runs.
  SAP Notes: Check SAP Notes for any known issues or fixes related to the PPH_MRP407 error message.
  Performance Considerations: Running MRP for a large number of materials can impact system performance, so it's advisable to plan during off-peak hours if possible.
