In this example, all volunteers who work "Emergency" jobs will get 50% of those worked hours as bonus hours. VSys lets you do this using the Bulk Value Updater in the User tools panel. (Note that bonus hours can be automatically calculated using Bonus hours crediting rules, we're just using this as an easy-to-understand example.)
Within the Bulk Value Updater, set Items to update to Hours, and Action to Update records.
Put filters on your hours to select just the appropriate records, in this example, the job groupEmergency, and the time window.
Click on the (add a field to be changed) link to bring up the first set of change steps.
Under Field to be updated, choose Bonus duration and change Get value from to Duration.
Click Save.
Click on the (add a field to be changed link) again to configure the second change. This is what we described as chaining values: first one set of changes are made and then the next.
Under Field to be updated, choose Bonus duration and change it by multiplying it by 0.50.
Then click Save again.
Click on Get items to update. Verify that the hours records shown are the appropriate ones.
If they are in fact correct, click on Run to update these hours records.
