PIC01090 - Details

• 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
