• What is the cause and solution for SAP error message WTADDI211 - Invalid follow-on operation for ordering additionals ?

  The SAP error message:
  WTADDI211: Invalid follow-on operation for ordering additionals
  
  Cause:
  This error occurs when you attempt to perform a follow-on operation (such as goods receipt, invoice verification, or delivery) on an additional item (an "ordering additional") in a purchase order or production order, but the system does not allow this because the additional item is not meant to be processed with follow-on logistics transactions.
  Ordering additionals are typically items added to a purchase order or production order that represent additional costs or services (e.g., freight, insurance, handling charges) rather than physical goods. Since these items do not represent stock or physical goods, follow-on operations like goods receipt or delivery are invalid.
  
  Explanation:
  
  Ordering additionals are used to capture additional costs related to procurement or production.
  They are not stock items and do not have material movements.
  Follow-on operations such as goods receipt (GR), invoice verification (IV), or delivery creation are only valid for stock items or services that require such processing.
  Attempting to create a follow-on document for an ordering additional triggers this error.
  
  
  Solution:
  
  Check the item category of the line item in the purchase order or production order:
  
  Ordering additionals usually have a specific item category (e.g., TAS for ordering additional in MM).
  
  
  Do not perform follow-on logistics transactions (like GR or delivery) for ordering additional items.
  Process ordering additionals only in invoice verification if applicable:
  
  Ordering additionals can be invoiced but do not require goods receipt.
  
  
  If you mistakenly tried to create a follow-on document for an ordering additional, correct the process by:
  
  Removing the ordering additional from the follow-on operation.
  Or, if the item should be a stock item, correct the item category in the purchase order.
  
  
  Review the business process to ensure ordering additionals are handled correctly:
  
  They are typically settled via invoice verification only.
  No goods movement or delivery creation should be attempted.
  
  
  
  
  Related Information:
  
  Item categories in purchasing documents define how items behave in follow-on processing.
  Ordering additionals are often used to capture freight, insurance, or other ancillary costs.
  In MM (Materials Management), ordering additionals have item category TAS.
  In SD (Sales and Distribution), similar concepts exist for additional costs but are handled differently.
  SAP Note and documentation on item categories and follow-on processing can provide more details.
