Previously, when an event was complete, you had two choices: either click the “Update All” button which would give every participant credit for every related requirement, or you could drill down on each related badge, then go into “In Bulk” editing and check the requirements off one-by-one or column-by-column (and then repeat for the next related badge).
There were two serious problems with these approaches… first off, there was no record of whether credit was given. So you could increment a youth's tally (e.g., nights away, or hours of hiking) over and over again, for the same event. The smarter solution is to record that a youth has had their tally incremented by participation, and thereafter prevent “double dipping”.
The second issue is that the “Update All” approach is overly generous, e.g., if a small number of your youth participated in a Scouts Own at camp, then not all the youth ought to get credit for it. So this generally meant that even though all the youth deserved credit for participating in the camp activities, the fact that a couple of youth shouldn't get credit for a particular requirement meant that you had to do the manual approach to updating (which incurred the risk of double-dipping, if you forgot what you had already given credit for).
So to make the whole process easier and less prone to errors, instead of a “Update All” button there is now an “Update…” button that takes you to an In Bulk editor that includes all the youth and ONLY the related requirements. There is an “All” button that will instantly select all requirements for all participating youth, but you can then deselect specific requirements (e.g., the four youth who didn't participate in the Scouts Own). Furthermore, updates that you may have already credited are shown with a “X” in the background to indicate that you don't need to give any further credit. Indeed, the “All” button won't select such already-credited reqs, so you can't accidentally double-dip.
Also, the “History” report now shows which event was associated with the update to the database. I.e., the rows of the History report will say (for example), “Marked as completed by participation in “Spring Group Camp 2012'” (and the name of the event is a hyperlink to the particular event).
Finally, when in the “In Bulk” editor, there is now a “Legend” link that will pop up a legend of all the symbols formatting used.
