• What is the cause and solution for SAP error message WSTI_MODEL000 - Material List contains no item ?

  SAP Error Message:
  
  WSTI_MODEL000 Material List contains no item
  
  Cause:
  This error occurs when you try to process or generate a model (e.g., a product model, variant configuration, or a BOM structure) in SAP, but the system finds that the material list (such as a BOM or a list of components) is empty or does not contain any items. Essentially, the system expects at least one material/component in the list to proceed, but none are found.
  Common scenarios include:
  
  Attempting to create or process a configurable material without any assigned components.
  Generating a sales order or production order for a configurable product where the BOM or variant configuration is incomplete or missing.
  Using transaction or functionality that requires a material list (e.g., variant configuration, model BOM, or product structure) but the underlying data is not maintained.
  
  
  Solution:
  
  
  Check the Material Master and BOM:
  
  Verify that the material master record is correctly maintained.
  Check if the BOM (Bill of Materials) for the material exists and contains components.
  Use transaction CS03 (Display BOM) to confirm that the BOM is not empty.
  
  
  
  Check Variant Configuration:
  
  If the material is configurable, ensure that the variant configuration is properly set up.
  Verify that the characteristics and dependencies are correctly maintained.
  Use transaction CU50 or CU51 to check the configuration model.
  
  
  
  Maintain Material List:
  
  If you are working with a model or configurable product, ensure that the material list (component list) is maintained.
  Add the required components to the BOM or configuration model.
  
  
  
  Review the Process or Transaction:
  
  Confirm that the correct material or model is selected.
  If you are using a custom program or report, check that the input data includes a valid material list.
  
  
  
  Recreate or Update BOM/Configuration:
  
  If the BOM or configuration is corrupted or incomplete, recreate or update it.
  Use CS01 to create a BOM or CU41 to create/update configuration profiles.

  Summary:
  The error WSTI_MODEL000 Material List contains no item indicates that the system expected a list of materials/components but found none. To resolve it, ensure that the BOM or variant configuration for the material is properly maintained and contains at least one item. Verify the material master, BOM, and configuration data, and correct any missing or incomplete entries.
