Display standard Set Types in CRM

Hi

I am not able to display the details (attributes) of some of the standard set types (for ex: COMM_PR_SRV, ) in CRM. I get the following error

You tried to display set type COMM_PR_SRV. This set type was not created using transaction COMM_ATTRSET and therefore can also not be displayed with this transaction.

If someone knows how to display them, kindly let me know.

For some standard set types for ex: CRMM_PR_SRVENT, assigned attributes can be displayed.

I think the problem is with ONLY those set types whose name starts with 'COMM'.

Regards,

Mahesh
