Another Thanksgiving Email

Here is another email we got Wednesday from a Dodeca Excel Add-In for Essbase customer.  This customer has a lot of VBA macros running some automation with Essbase and asked for some assistance.  We told it was as easy as replacing they Essbase function declarations file with our Dodeca Add-In  function declarations file, and then setting the variables that contain the location for the Dodeca-Essbase server.  In other words, replace this file:
