  SAP Error Message:
  
  WTY154 - Generation of new items from selected item & is not possible
  
  Cause:
  The error message WTY154 occurs in SAP when you attempt to generate new items (such as delivery items, billing items, or follow-on documents) from a selected item, but the system determines that this action is not allowed or possible. This can happen due to several reasons, including:
  
  The selected item is already fully processed or closed (e.g., fully delivered, fully billed).
  The item is not eligible for follow-on document creation due to its status or configuration.
  The item is part of a document type or sales process that does not support generation of new items.
  Missing or incorrect master data or customizing settings that prevent item generation.
  The item is flagged as non-deliverable or non-billable.
  The system logic or user exit/custom code restricts the creation of new items from the selected item.
  
  
  Solution:
  To resolve the WTY154 error, consider the following steps:
  
  
  Check Item Status:
  
  Verify the status of the item in the sales document or delivery.
  Ensure the item is not fully processed (e.g., fully delivered or billed).
  If fully processed, no new items can be generated.
  
  
  
  Review Document and Item Category Settings:
  
  Check the sales document type and item category configuration in SPRO.
  Confirm that the item category allows follow-on document creation.
  Verify that the item category is not set as non-deliverable or non-billable if you are trying to create delivery or billing items.
  
  
  
  Check Master Data:
  
  Verify the material master data for the item.
  Ensure the material is active and allowed for the intended process (delivery, billing, etc.).
  
  
  
  Analyze Customizing and User Exits:
  
  Review any custom code or user exits that might restrict item generation.
  Check for any enhancements or BAdIs that influence item creation logic.
  
  
  
  Check for Partial Processing:
  
  If partial delivery or billing is allowed, check if the remaining quantity is zero.
  If no quantity remains, new items cannot be generated.
