• What is the cause and solution for SAP error message PIC01090 - MPN-MRP set &1 (&2) split into the sets &1 (&2) and &3 (&4) ?

  The SAP error message PIC01090 indicates that a Material Planning (MPN) set has been split into two separate sets during the planning process. This typically occurs in the context of Material Requirements Planning (MRP) when the system identifies that the MPN (Manufacturer Part Number) set cannot be processed as a single entity due to certain conditions or configurations.
  Cause:
  
  Configuration Issues: The MPN set may have been configured incorrectly, leading to inconsistencies in the data.
  Data Inconsistencies: There may be discrepancies in the master data associated with the MPN, such as different planning parameters or characteristics.
  Material Variants: If the MPN set includes materials with different characteristics or variants, the system may split them to handle the planning requirements appropriately.
  Planning Parameters: Different planning parameters (like lot size, lead time, etc.) for the materials in the MPN set can cause the split.
  
  Solution:
  
  Review MPN Configuration: Check the configuration of the MPN set in the system. Ensure that all materials included in the set have consistent planning parameters.
  Check Master Data: Verify the master data for the materials involved. Look for inconsistencies in the material master records, such as different MRP types, lot sizes, or procurement types.
  Analyze Planning Parameters: Ensure that the planning parameters for all materials in the MPN set are aligned. If there are differences, consider standardizing them where appropriate.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on MPN configuration and planning.
  Testing: After making adjustments, run a test MRP run to see if the issue persists. Monitor the results to ensure that the MPN set is processed correctly.
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional guidance.
  Transaction Codes: Familiarize yourself with transaction codes related to MRP and MPN management, such as MD01 (MRP Run) and MM02 (Change Material).
  User Forums: Engage with SAP community forums or user groups to see if others have encountered similar issues and what solutions they found effective.
  SAP Help Portal: Utilize the SAP Help Portal for detailed documentation on MPN and MRP processes.
  
  By addressing the underlying causes and ensuring that the configuration and data are consistent, you can resolve the PIC01090 error and improve the planning process for MPN sets in SAP.
