# Added: Warning when editing a co-worker's schedule When trying to adjust an existing schedule, there will now appear a warning : "Changing existing schedule can cause errors in historical data. Consider adding a new schedule instead of editing old to avoid this." This is to limit the possibility of banked hours being incorrect, and also for Moment to not calculate the balance for banked hours in a wrong way - for example in reports. Therefore it is necessary that the defined working hours are correctly registered and important to maintain an accurate history of the employee. ![](https://lh6.googleusercontent.com/UIIYpAA1kDBoy2d6iZdS5PL_fC3-dP_xwQkoHRKwNu-uPqLC-r8wprLxBPWDcYUNOg1JoO-1OeCGt0OrwJBm2_SUp2usanLVqUsHSna1VdG5T-szYEBuF4TL3d4JJUbZVSCKq3cm) ![](/files/vuGJISdNYyKJEytyBoRx) If you have any questions please contact **** --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
