Product Configure Error

I'm Trying to Configure my custom Product in sap crm ehp2.

I was created Attribute,setype,hierarchy  and Category.

But When  I Trying to configure Product in COMMPR01.

It is giving Error Data cannot be maintained for set type COMM_PR_SHTEXT, COMM_PR_UNIT.

So I tried to Add Set type : COMM_PR_SHTEXT

But this was not in the list of Set Types.

Please Guide me how to come out of this ......

Thanks.
