  Cause:
  This error message indicates that there is an attempt to change the supplier associated with a purchase requisition (PReq) that is not allowed. The reasons for this could include:
  
  Status of the Purchase Requisition: The PReq may be in a status that does not allow changes, such as being already converted into a purchase order or being in a completed state.
  Authorization Issues: The user may not have the necessary permissions to change the supplier for the specified PReq.
  Data Integrity Constraints: There may be business rules or configurations in place that prevent changing the supplier once certain conditions are met (e.g., if the PReq has been approved or if it is linked to specific contracts).
  System Configuration: The system may be configured to restrict changes to suppliers for certain types of requisitions or under certain conditions.
  
  Solution:
  To resolve this error, you can consider the following steps:
  
  
  Check the Status of the PReq: Verify the current status of the purchase requisition. If it is already converted to a purchase order or is in a completed state, you may need to create a new PReq instead of modifying the existing one.
  
  
  Review User Authorizations: Ensure that the user attempting to make the change has the necessary authorizations to modify the supplier information for the PReq.
  
  
  Consult Business Rules: Check if there are any specific business rules or configurations that prevent changing the supplier. This may involve consulting with your SAP functional team or reviewing the configuration settings in the system.
  
  
  Create a New Purchase Requisition: If changing the supplier is not possible due to the status or business rules, consider creating a new purchase requisition with the desired supplier.
  
  
  Contact SAP Support: If the issue persists and you cannot identify the cause, consider reaching out to SAP support for further assistance. They may provide insights based on the specific configuration and version of your SAP system.
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as ME51N (Create Purchase Requisition), ME52N (Change Purchase Requisition), and ME53N (Display Purchase Requisition) to manage PReqs effectively.
  Documentation: Review SAP documentation related to purchase requisitions and supplier management for additional context and guidelines.
  User Forums: Engage with SAP community forums or user groups where similar issues may have been discussed, providing insights or solutions from other users' experiences.
