The date of the next examination is calculated automatically based on the date and type of the medical examination, in other words, on the number of months entered in the miscellaneous table no. 395 – Type of medical examination. If the number of months is equal to 0 (for example, for a medical examination of type ‘VIP’ - Information and Prevention examination), the date of the next examination is not calculated automatically. You can enter it manually.
