Where is the MDX code stored?

[Exhorter]

Here is my issue:

I am using 2013 excel and my data connection is to a cube. I use a few MDX codes to access the data in the cube. For some reason, my MDX set is in my pivot table but not in my list for sets connected to the cube.

Does anyone know where the MDX data is stored in the xml of the workbook? Or is it stored somewhere differently?

Thanks,

Exo
