I have 2 dimensions with same fields, want to use other one in chart.

[#1]

Hi community,

I have two dimesions with the same field values but in different tables.  I can't link them in the script for other reasons.  Is there away I can use the other one as the dimension for a graph? 

The dimension I have that works is el1_sname but I'd like to use [Division Abbreviation].  Here is my expression:

sum({ $< balcode3={'ACTUAL'},

LinkYear= {$(=$(vCurrentFiscalYear))},

LinkMonth=CurrentDocumentMonth3,

el2={'17020','17030','78010','78020','78030','78040','78050','78060','78070','78220'},

el3={">=1999"},

[code3]={'RBIACCT'}

             >}

             Tot3)

I tried adding something like el1_sname={"division abbreviation"}, to the expression but that didn't work.  Is there something similar that I might do?
