The Pull-up is used in any situation where an input data map might not be present. If that is the case, a reference input is used instead. It is intended to be useful primarily for Macro creators.
It has two inputs, the Reference and Override input. If data is present on the Override input, that data will be sent on to the output. Otherwise, the data from the Reference input is sent.
- Use to allow optional parameters for your macros. If the user doesn’t provide something, you can use your own default.
