Insert..Select Statement Problem

Hi,

I am trying to run the following insert statement, but am gettng an error. The table I want to insert to
(DimensionMonthTime_hold) has an
Identity column defined for its key.

The part I cannot figure out is that when I run this insert statement without the order by statement, the insert is successful. If I attempt to run this insert statement with the Order By statement, I get an error saying that I have to provide a value for the identity value in the insert statement (which i don't want to do.) I need to have the data sorted, hence the reason for the order by.

I've tried to specify the column names on the insert line, but haven't figure that out.

Any suggestions?

Thanks

Jim
