The inbox and jobs databases contain (sub)forms with Notes fields that have the following prefix: $N2PDF. These fields will be “recognized” by the server task and interpreted according to the corresponding information.
The “n2pdfJobs.nsf” database provides the easiest way (for users, for example) to create jobs for the server task. However, you can also create standard jobs directly in “n2pdfInbox.nsf.” To do this, generate a document there using exactly the same field names as in this database. This way, you can design how jobs will be generated from your own database, for example.
