  The SAP error message MDG_MDF315 indicates that there is an issue with the hierarchy configuration for a characteristic in the Master Data Governance (MDG) module. Specifically, it states that only one hierarchy is allowed for the specified characteristic (denoted as &1).
  Cause:
  This error typically occurs when:
  
  You are trying to assign multiple hierarchies to a single characteristic, which is not permitted in the system.
  There may be a configuration issue where the characteristic is incorrectly set up to allow multiple hierarchies.

  To resolve this error, you can take the following steps:
  
  
  Check Hierarchy Assignments:
  
  Go to the configuration settings for the characteristic in question.
  Verify if there are multiple hierarchies assigned to the characteristic. If so, you need to remove the additional hierarchies and ensure that only one hierarchy is assigned.

  Consult Documentation:
  
  Review the SAP documentation related to MDG and hierarchy management to ensure that you are following best practices and guidelines.
