The number of mapping lines that can be used to connect transformation-source nodes, transformation-destination nodes, and functions is predetermined.

The following table lists the number of mapping lines that can be connected as outputs.

Table 6-16 Number of mapping lines that can be connected as outputs

Node or function	Number of mapping lines that can be connected
Transformation-source node	Multiple#1
All functions	1#2

#1

There is no upper limit.

#2

For the set constant function, you can connect as many mapping lines as required.

The following table lists the number of mapping lines that can be connected as inputs.
