Restricting the material types in MM01

Question

Dear experts,
Our client is using few materila types like-HIBE,NLAG,ROH
We have upgraded from 4.6B to ECC6. Now many other material types have come .
While creating material in MM01,selecting the required material type among the many is inconvient.
1)One way of removing the unnecessary mat types is deleting others in OMS2,
The other way of restricting is --
2) I can enter the authorisation group in OMS2 for the required material types and i can assign to M_MATE_MAR object in the required role, but it is not working
Do i need to create authorisation group in any customisation for entering in the OMS2, because what i entered in OMS2 is not displaying in PFCG of the authorisation object under authorisation group.I have checked in SM30 also ,the same authorisation groups under T134 table are updated. Even though,mat types are not restricted in MM01 under material type field.
Please suggest any other way of restricting the display of material types in Material type field of MM01 instead of deleting unwanted the material types in OMS2 transaction
Regards,
Dayanand
