Ok, this is simple, but I will not give you the complete code. Below is a template of what your code should look like and where to put it.

On the Onvalidate trigger of your Boolean field in the table add your check.
Your code should look something like this:

IF <yourbooleanfield> THEN BEGIN
  IF not <your check> THEN BEGIN
    ERROR('Error Message');
  END;
END;

The ERROR command will automatically reset the entered value.

I hope this helps.

If you wish it to silently uncheck without an error message you can simply call ERROR('').

Also you may be tempted to do something like the following:

IF <yourbooleanfield> AND (NOT <your check>) THEN
    ERROR('Error Message');

Don't do that, because Navision evaluates both sides of an AND operation even if the left evaluates FALSE. Of course, if your check procedure already checks to make sure the value in the boolean is true before running its logic, then you could safely condense the code to:

IF NOT <your check> THEN
    ERROR('Error Message');

It really depends on what you are doing.
