While closing the periods I got following error.
"Mode: Check and close period
Period entered (month/year):052006
Incorrect period in control rec. of CoCd 2000; no conversion
The current period (month/year) of the control record is052006"
While entering the month which I want to close( 05/2006) It gives a warning Message as "The specified year 2006 is not the current calendar year".
