Application Diagnostics - Requisition Checks - Account Generator

Hello,

I'm trying to run one of the Oracle Application Diagnostics.  It's the Account Generator test under Requisition Checks.

One of the required inputs is the Destination Organization Code:

I have found a Destination Organization and a Destination Organization ID, but the test fails when I use them.  Where would I find the Destination Organization Code?

Thanks,

Debby
