  The SAP error message AG028 indicates that the product availability check is switched off for a specific material in a particular plant. This means that the system is not performing availability checks for that material, which can lead to issues in order processing, inventory management, and overall supply chain operations.
  Cause:
  
  Configuration Settings: The availability check for the material may have been intentionally disabled in the material master data or in the configuration settings for the plant.
  Material Master Data: The material may be set up in such a way that it does not require an availability check, possibly due to its type (e.g., non-stock material).

  Solution:
  
  
  Check Material Master Data:

  Review Configuration Settings:
  
  Use transaction code SPRO to access the configuration settings.
  Navigate to Logistics Execution > Shipping > Availability Check > Define Availability Check.
  Ensure that the availability check is configured correctly for the relevant material types and plants.
  
  
  
  Check Sales Order or Delivery:
