I just upgraded from SA2008 to SA2009 Premium for the purpose of departmentalizing my different properties and am on the dreaded learning curve.  I have set up each customer and vendor with their respective departments.  Do I now have to edit the basic AR  and AP account so the balances to date do NOT appear in the "unassigned" area?  Does this setup default to the GST accounts as well?

what is the point in departmentalizing GST via the AP and AR modules?  It seems by virtue of the setup in clients and vendors screens that this is automatic.  doesn't this just complicate a simple in ad out process?

What does this error message mean and does it need correction?  The department 0010, Chinook, cannot be removed from this account since it is being used as part of this account's linked account.  If correction is needed how and where?

thanks for all advice
