  SAP Error Message:
  W5124 Field & could not be changed in PO item & &
  
  Meaning / Cause:
  This warning message occurs when you try to change a field in a Purchase Order (PO) item that is not allowed to be changed due to system or business logic restrictions.
  Common causes include:
  
  The PO item is already processed or partially processed (e.g., goods receipt or invoice receipt posted).
  The field is controlled by the system and locked after certain processing steps.
  The field is dependent on other data that restricts changes.
  The PO is in a status that does not allow changes to that particular field.
  The field is part of a reference document or contract where changes are restricted.
  
  
  Typical Fields That Cannot Be Changed:
  
  Material Number
  Plant
  Account Assignment Category
  Purchasing Group (in some cases)
  Delivery Date (if goods receipt already posted)
  Price (if invoice receipt already posted)
  
  
  Solution / How to Resolve:
  
  
  Check PO Status:
  
  Verify if the PO or PO item has already been partially or fully processed (e.g., goods receipt or invoice receipt posted).
  Use transaction ME23N to display the PO and check the item history tab.
  
  
  
  Check Document Flow:
  
  If the PO is referenced by other documents (e.g., contracts, scheduling agreements), some fields may be locked.
  Review related documents and their statuses.
  
  
  
  Use Change Restrictions:
  
  Understand that some fields are intentionally locked to maintain data consistency.
  If a change is necessary, consider canceling or reversing related documents (e.g., cancel goods receipt or invoice receipt) before making changes.
  
  
  
  Create a New PO or PO Item:
  
  If changes are not possible, create a new PO or new PO item with the correct data.
  
  
  
  Consult Customizing or Development:
  
  Sometimes, user exits or BAdIs enforce additional restrictions.
  Check with your SAP MM consultant or developer if custom logic is preventing changes.
  
  
  
  Check Authorization:
  
  Ensure you have the necessary authorization to change the PO fields.
