The Before bulk share script section also allows you to cancel a bulk share from running if your script contains:
cancel = true;
That is, if after evaluating the script, there is a cancel variable and its value is set equal to true, then the bulk share will cancel from running.
This may be useful for when you only want the bulk share to run if certain conditions are met and you prefer to create/check for these conditions using server side javascript instead of the condition builder.
