member attribute

In our report we have a member "Maintenance Order" with the attributes "Work Center" and "Order Type". Is it possible to show only the attributes in the report and not the member?

When I create the report I have:

column A - Maintenance Order

column B - Order Type

column C - Work Center

But I want:

column A - Order Type

column B - Work Center

Can I do this with the attributes or do I need to create new members for "Order Type" and "Work Center"?

Kind regards,

Lieselot
