  The SAP error message NR106 ("Select only one group for assignments") typically occurs in the context of number range management, particularly when you are trying to assign number ranges to a specific object or group in SAP. This error indicates that the system expects you to select only one group for the assignment, but it appears that multiple groups have been selected.
  Cause:
  The error is usually caused by one of the following scenarios:
  
  Multiple Selections: You have selected more than one number range group when the system only allows a single selection for the assignment.

  Review Number Range Configuration:
  
  Navigate to the number range configuration settings in SAP (Transaction code: SNRO).
  Check the settings for the relevant object and ensure that the number range groups are correctly defined.
