Start Sub Flow

This flow indicates a starting point of a flow-path that can be used from other flows. At the end, the result of the flow will be sent back to the calling flow.

It has the following configuration options:

Name: here you can specify the name that has to be used to call this starting point.
Input parameters: in this table you can define the parameters that need to be specified by callers from this flow.
Check Input parameters: if you select this checkbox, the input parameters are checked, and only the ones defined in the Parameter List will be copied and used. Also, the Sub Flow will not be started if a required parameter is not specified. This removes the need to handle missing parameters in your sub Flow. However, in some cases (for example when you use the Sub Flow as a mechanism to simplify a single large workflow), your Sub Flow will only be called from one place, and you want access to any/all variables in the calling workflow. If you leave this checkbox unselected, the input parameters are not checked.
