3.5.6 Scenarios where relational lines cannot be drawn

Relational lines that form a loop

You cannot use relational lines in a way that creates a loop within a flow.

Relational lines that connect a step to itself

You cannot draw a relational line if the source and destination steps of the line are the same.

Identical relational lines

You cannot create parallel relational lines with the same source and destination step.

Multiple inputs to a branch by returncode plug-in

Because a branch by returncode plug-in judges the return value of the preceding step, you cannot draw relational lines to such a plug-in from multiple steps. Only one step can serve as the preceding step of a branch by returncode plug-in.

Connecting a branch by returncode plug-in or branch by property value plug-in to a branch by returncode plug-in or branch by property value plug-in

You cannot draw a relational line that connects a branch by returncode plug-in or branch by property value plug-in to a branch by returncode plug-in or branch by property value plug-in. However, you can connect such a plug-in as a succeeding step.

Relational lines from a branch destination step of a branch by returncode plug-in or branch by property value plug-in

A branch by returncode plug-in or branch by property value plug-in can only have one branch destination step, which cannot be connected further by a relational line. If you need to use several steps, draw a connection line to a flow plug-in.

Relational lines to a branch destination step of a branch by returncode plug-in or branch by property value plug-in

You cannot draw a relational line to the branch destination step of a branch by returncode plug-in or branch by property value plug-in.
