This setup code identifies one of the parameters converted to the EDM software when it was submitted. It is then sent, along with its value, to the EDM software every time the document is submitted.
Moreover, in the call context, the software creates a variable whose name corresponds to the code prefixed by G_.
Thus, for example, if the parameter identifying the submitted document is called DOC_ID, a variable G_DOC_ID will be available in the calling context, so it will be possible to use this variable in a formula defining a reference for the document to be archived in the software after it submission.
