## Event Guidelines

Use the mobile app or the web version of PULSE to enter events! Tap Events in the [mobile app](docId\:LrbWjLC6pBiEQt-JRs1XB) to get started, or see [Add Events](docId\:e-WCEtRy4dtmIOd-iy-k4) to learn more about adding events from web. PULSE supports adding events that have occurred within the last year.

## Process Changes

When you add events from web or the mobile app, your updates are sent to PULSE and then on to DairyComp 305 for DairyComp Unlimiteddairies (WiFi or data connection required).

- If you have not selected the Sire and/or Breeding Code for an animal in this event, the app will not include that animal when it sends the batch DNB event update to PULSE.
- Any incomplete animals will remain visible in the mobile app DNB event until you either remove them from the list or finish defining their details and process the changes again.
