Extend serial's warranty

By default, warranty is calculated automatically, based on fields on serials:

Conditions, that apply are (warranty enabled):

• if serial is not sold (this is necessary to show correct data in calibrator)
• if sold serials do not need calibrations (image below)
• if sold serials need calibration and are calibrated (last calibration is before current date and next calibration is after)
  
• if warranty is valid until the warranty due on serial number. This is generated from sales date to calculated date from product setting warranty duration in months (image below)

Warranty will turn off, when warranty due date passes or calibration was not done within N months from next calibration date (the N can be setup in ERP settings).

You can turn on warranty with warranty switch on serial's page. Be aware of automation explained in section below:

Warranty will turn off every night, if settings are not correctly set up (e.g. warranty due or next calibration is missing based on conditions above)

Calibration interval can be changed, if calibration is necessary more or less often. Zero mean 12 months.
