  Error Message
  WS751 - Item without material not configurable
  
  Cause
  This error occurs in SAP Variant Configuration (LO-VC) when you try to configure a sales document item that does not have a material assigned, but the system expects a material to be present for configuration.
  In SAP, variant configuration is linked to materials that have configurable characteristics. If an item in a sales document (e.g., sales order, quotation) does not have a material number, the system cannot determine which configuration model to use, hence it throws this error.
  Typical scenarios causing this error:
  
  The sales document item is created without a material number.
  The item is intended to be configurable, but the material field is empty.
  Custom developments or user exits incorrectly manipulate item data and clear the material field.
  The item category used requires a material but none is assigned.
  
  
  Solution
  To resolve the WS751 error, consider the following steps:
  
  
  Assign a Material to the Item:
  
  Ensure that every configurable item in the sales document has a valid material number assigned.
  Check the item category settings to confirm that the item category requires a material.
  
  
  
  Check Item Category Configuration:
  
  Verify that the item category used allows configuration and requires a material.
  If you want to allow items without materials, use an appropriate item category that supports this scenario (though variant configuration typically requires a material).
  
  
  
  Review Custom Code/User Exits:
  
  If there are user exits, BAdIs, or enhancements that manipulate sales document items, check if they inadvertently clear or fail to assign the material number.
  Correct the logic to ensure the material is always assigned for configurable items.
  
  
  
  Sales Document Data Consistency:
  
  Check the sales document for data inconsistencies.
  If the item is a text item or service item without a material, ensure it is not marked as configurable.
  
  
  
  Master Data Check:
  
  Confirm that the material master exists and is maintained correctly for the configurable material.
  The material should be flagged as configurable (e.g., with a configuration profile).
