• What is the cause and solution for SAP error message WTY129 - You have not entered an item type ?

  SAP Error Message:
  
  WTY129 - You have not entered an item type
  
  Cause:
  This error occurs when you are trying to process a transaction (often in the context of sales orders, deliveries, billing documents, or similar processes) and the system expects an item type to be specified, but it has not been entered. The item type is a mandatory field that defines the nature of the item (e.g., standard item, free-of-charge item, text item, service item, etc.) and controls how the system processes the item.
  
  When does it typically occur?
  
  Creating or modifying sales documents (e.g., sales orders, quotations).
  Entering items in delivery or billing documents.
  Custom transactions or user exits where item type is required but missing.
  Data migration or interface scenarios where item type is not mapped or passed correctly.
  
  
  Solution:
  
  
  Enter the Item Type:
  
  When creating or editing the document, ensure that the item type field is filled in for each item line.
  The item type is usually a two-character code (e.g., TAN for standard item in sales order).
  
  
  
  Check Default Item Type Configuration:
  
  If the item type is not defaulting automatically, check the configuration in the sales document type or item category determination.
  Transaction codes like VOV7 (Sales Document Types) and VOV6 (Item Categories) are relevant.
  Ensure that the item category determination procedure is correctly set up so that the system can determine the item type automatically based on the material, sales document type, and other factors.
  
  
  
  Review User Exits or Enhancements:
  
  If custom code is involved, verify that the item type is being set correctly in the user exit or BAdI.
  Missing assignment or incorrect logic can cause this error.
  
  
  
  Data Migration / Interface Checks:
  
  If data is being uploaded or interfaced, ensure that the item type field is correctly mapped and populated.
  
  
  
  
  Related Information:
  
  Item Type / Item Category: Controls pricing, delivery relevance, billing relevance, and other processing rules.
  Sales Document Types: Define which item categories are allowed.
  Transaction Codes:
  
  VA01 - Create Sales Order
  VA02 - Change Sales Order
  VOV6 - Define Item Categories
  VOV7 - Define Sales Document Types
  
  
  SAP Notes: Check SAP OSS notes for any known issues related to WTY129.
  Debugging: Use debugging to check where the item type is expected and why it is missing.
  
  
  Summary:
  
  Cause: Item type not entered or missing in the item line.
  Solution: Enter the item type manually or fix configuration to default it automatically.
  Check: Sales document type, item category determination, custom code, and data interfaces.
