When generating documents through Plumsail processes, you can use a predefined token for inserting unique numbers.
To do that, add a token {{@number}}
to the template:
By default, it starts from 1
and then is incremented with each run.
Besides, you can use the token in other fields of the process configuration, i.e. in the output file name or in deliveries. If required, it is possible to set a custom value to start numbering with. In the output settings, unfold the Advanced section and set the Document number index field. The next process run will use an incremented value.
