Fix Labor Entry data input errors (after posting) u sing Job Ad

When possible, we try to do all our labor adjustments thru Labor entry. Our
accountant posts once a month and he waits until department managers give
him the OK to post. It is their responsibility to get all time reviewed for
accuracy Monday morning and he usually posts Monday afternoon. If we have
the problem where we cannot access an entry to correct it because of
posting, we do the adjustment thru Job Adjustments.
