If using a Jitterbit-provided plugin, reference the documentation for each plugin available under Plugin Library to determine which global variables are required or optional and what to set them to.
NOTE: Global variables are referred to as data elements within the plugin XML manifest files for Jitterbit-provided plugins.
If a plugin does not have any variables that are required, it is not necessary to set global variables in a script unless there are other optional variable values you want to provide.
Setting Global Variables for the Plugin
Prior to executing a plugin that is applied to an activity or called from a script, you must initialize any variables that are required by the plugin. This is normally done by creating a script to set these values that is upstream of the plugin in the operation chain. If calling a plugin from a script, you may set the global variable values in the same script or a different script, so long as they are initialized before the plugin is run.
