• What is the cause and solution for SAP error message 88928 - Component quantity for &1 <= zero -> substructure will not be expanded ?

  The SAP error message 88928, which states "Component quantity for &1 <= zero -> substructure will not be expanded," typically occurs in the context of Bill of Materials (BOM) or production order processing. This error indicates that there is a component in the BOM or a related structure that has a quantity set to zero or less, which prevents the system from expanding the substructure.
  Cause:
  
  Zero or Negative Quantity: The most common cause is that one or more components in the BOM or the production order have a quantity that is either zero or negative.
  Incorrect BOM Configuration: The BOM may have been incorrectly configured, leading to invalid component quantities.
  Data Entry Errors: Manual data entry errors during BOM creation or modification can lead to incorrect quantities.
  Master Data Issues: Issues with the material master data or the configuration of the components can also lead to this error.
  
  Solution:
  
  
  Check BOM Configuration:
  
  Go to the BOM transaction (e.g., CS03 to display BOM) and check the component quantities.
  Ensure that all components have valid quantities greater than zero.
  
  
  
  Correct Component Quantities:
  
  If you find any components with zero or negative quantities, update them to the correct values.
  You can do this in the BOM maintenance transaction (CS02 for change).
  
  
  
  Review Production Orders:
  
  If the error occurs in the context of a production order, check the order for any components that may have been incorrectly defined.
  Ensure that the order references a valid BOM with correct component quantities.
  
  
  
  Check Material Master Data:
  
  Verify that the material master data for the components is correctly set up and does not have any inconsistencies.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or help resources for any specific notes related to this error message.
