  The error message MM_PUR_PR_EXT_MSG008 in SAP S/4HANA indicates that the system is not configured to function as a hub system for managing purchase requisitions. This typically occurs in scenarios where the system is expected to handle external procurement processes but is not set up correctly to do so.
  Cause:
  
  System Configuration: The SAP S/4HANA system is not configured as a hub system. This means that it is not set up to manage external purchase requisitions or to communicate with other systems in a hub-and-spoke architecture.
  Integration Issues: There may be issues with the integration settings between the S/4HANA system and other systems (like SAP Ariba or other procurement systems).
  Missing Authorizations: The user may not have the necessary authorizations to perform actions related to external purchase requisitions.
  
  Solution:
  
  
  Check System Configuration:
  
  Ensure that the S/4HANA system is configured as a hub system. This involves checking the settings in the system configuration (transaction SPRO) under the relevant procurement and integration settings.

  Review Integration Settings:
  
  If you are integrating with other systems (like SAP Ariba), ensure that the integration settings are correctly configured. This may involve checking middleware settings or ensuring that the necessary connections are established.
