We collect data by day and by hour. But our administrative department processes the information by period. Sometimes some employees have outside contracts and so their hours change. The number of hours for a period goes from X to Y and back to X.
For the moment, each case is automated according to conditions. (Information coming from the employers) But good boss, sometimes wants to change the total hours of a period directly and that all applies to the period.
In the example, he wants to change directly the 70 and not the 7… any idea ?
