  The SAP error message ME028 ("Field selection & not defined") typically occurs in the context of purchasing documents, such as purchase orders or purchase requisitions. This error indicates that a field selection for a specific field has not been defined in the system, which can prevent users from completing their tasks.
  Cause:
  
  Field Selection Configuration: The error usually arises when the field selection for a particular document type or purchasing organization is not properly configured in the system. This can happen if the field is not marked as required or optional in the configuration settings.
  Missing Customization: If the system has been customized and certain fields have been added or modified, the necessary field selection criteria may not have been updated accordingly.
  User Authorizations: Sometimes, the error can also be related to user authorizations, where the user does not have the necessary permissions to access or modify certain fields.

  Check Field Selection Configuration:
  
  Go to the SPRO transaction (SAP Reference IMG).
  Navigate to Materials Management > Purchasing > Purchase Order > Define Field Selection for Purchase Orders.
  Ensure that the field in question is properly defined for the relevant document type and purchasing organization.
  Adjust the field selection settings as necessary (e.g., set the field to optional or required).
  
  
  
  Review Customizations:

  Consult with your SAP functional consultant or technical team to verify that the custom fields are correctly integrated into the field selection logic.
  
  
  
  User Authorizations:

  If needed, update the user roles to include the required authorizations.
  
  
  
  Testing:
