# 3.A.4 Call Process Tool

This action allows you to execute a [process tool](https://usermanual.vtenext.com/books/business-process-manager-manual/chapter/16-tool-processes).

Once the desired tool has been selected, the expected Input Parameters are loaded and can be configured using process variables, as usual.

Unlike sub-processes, this action does not have the same limitations and can be called multiple times within the same process and also from different processes.

Below is an example of a tool call used to add a comment to a ticket. The parameters are those defined in the process tool, which in this case are the ticket ID and the comment text.
