FMCC AAI setup

The FMCC document says that you need a series of AAIs in order to do the initial build/populate of the financial matrices.  It also says that the AAIs of F01 - F28 are already pre-installed/delivered with FMCC.

We have FMCC but we do not have these AAIs of F01 - F28.

1 - Should we have these?

Also, you never see a single letter AAI, such as “F”. 

You see FC, without any accounts associated with it, then FC01, FC02, etc.  FD without any accounts, then FD01, FD02.  F01 by itself just doesn’t seem right, unless its supposed to be FF01, FF02, etc.
