Checking out a rule
To avoid accidental rule changes or conflicts that might result from multiple developers working on the same rule, perform a check out, so that you can lock the rule and safely make changes to it. By checking a rule out before editing, you avoid unwanted rule changes, and as a result save time and maintain a better quality application.
Note: When
you make updates to your application in App Studio, automatically manages the check-in and checkout
process.
Note: You do not have to check in your changes immediately. You can log out and
return to a checked-out rule later or click Discard to remove the rule
from your personal ruleset.
