Help -> Create Support Message

We are running Solution Manager 7.1 SP6. 
Have performed most of the ITSM related setup/customization activity but may have missed something.

Issue/Question:

When I create an incident using the WebUI or the SOLMAN Workcenter, the incident is created as trans type ZMIN (copy of SMIN).

The SAPGUI function: Help -> Create Support Message, successfully creates an incident in Solution Manager but as trans type SMIN. 

What must I do to get this SAPGUI Create Support Message function to utilize ZMIN instead of SMIN?

Thanks
