Create local temporary table in procedure

Hi folks,

I have a procedure (I wrote in the procedure editor in Project Explorer).  In the procedure I'm trying to create a local temporary column table however when I attempt to activate the procedure I get error;

feature not supported: DDL is not supported in the READ ONLY procedure

In the past when I created a procedure via old method (via CONTENT/NEW PROCEDURE) I had the option of choosing READ or READ/WRITE.  I'm not seeing this option in the new procedure editor.  Also I noticed a second tab next to SQLScript tab called LOCAL TABLE TYPES.  I can't seem to place my create local temporary table there either.

I've read in other posts that this is possible... what do I need to do in order to be able to create and update this temp table?

Thanks,

-Patrick
