  The SAP error message 3G717, which states "Please do not use any underscores in type group names," typically occurs when you are trying to create or modify a type group in ABAP (Advanced Business Application Programming) and you have included an underscore (_) in the name of the type group.
  Cause:
  The error is caused by the naming convention restrictions in SAP.

  Check Naming Conventions: Ensure that the new name adheres to SAP's naming conventions for type groups. Typically, type group names should start with a letter and can be followed by letters and numbers.
