Create a non-database item (number datatype) which will hold number of checked checkboxes (let's call it CB_CNT (checkbox count)).

What is the initial state? Is the form empty (so you are supposed to enter new records), or do you fetch them (by executing a query) from the database and then do something (insert, update, delete)?

If it is empty, initial CB_CNT value is 0 (zero); in WHEN-CHECKBOX-CHANGED trigger increase (or decrease) CB_CNT item value.

If you fetch values from the database, count checkboxes that are already checked (you can do that by looping through block records, or - using GET_BLOCK_PROPERTY (LAST_QUERY) you can even find the WHERE clause and count that number). Once you have the initial state, you're back on WHEN-CHECKBOX-CHANGED trigger option.

Declare
V_Count Number := 0;
v_Record Number := :System.Cursor_Record;
Begin
First_Record;
Loop
If :Active = 'Y' Then
v_Count := V_Count+1;
End If;
Exit When :System.Last_record = 'TRUE';
Next_record;
End Loop;
Go_Record(v_Record);
if v_Count > 1 Then
Message('One Month Can Be Active at a Time');
:Active := 'N';
Raise Form_Trigger_Failure;
End If;
End;
