Funds Check Hold

 Need help - we are a government agency testing 12.1.1

In our current fiscal year I have created 9 invoices one for each of the periods open (Oct/09-10, Nov/09-10, Dec/09-10, Jan/10-10, Feb/10-10, Mar/10-10, Apr/10-10, May/10-10, & Jun/10-10).  I ensured that there were funds entered and avilable for the account I am using and check to ensure the AP and GL periods are all open.  I also checked that Budgetary Controls was enabled on the ledger.

So when I validate I have no issues until May/10-10 and after.  This is continuous and occurs in every test.  We can enter and validate invoices up to May/10-10.
