  The SAP error message MDG_BS_BP003 typically occurs in the context of Master Data Governance (MDG) for Business Partners (BP). This error indicates that the system is expecting an internal number assignment for the business partner and that an external number should not be entered.
  Cause:
  The error is triggered when a user attempts to manually enter an external number for a business partner during the creation or modification process, while the system is configured to automatically assign internal numbers.

  Solution:
  To resolve this error, you can follow these steps:
  
  
  Do Not Enter External Number: Ensure that you do not input any value in the external number field when creating or editing a business partner. Leave this field blank to allow the system to generate the internal number automatically.

  Navigating to the relevant customizing settings in the SAP system.
  Verifying the settings for number ranges and number assignment for business partners.
  Ensuring that the external number assignment is enabled if that is the desired behavior.
