Multi Join
The Multi Join macro joins up to five inputs on a given key field, using a Cartesian join. The input fields can (and should) be renamed on output using the Input prefix options to ensure that all output fields are unique. This macro outputs a single wide record containing all input fields, including both the joining and non-joining records. Whenever there is a key value that doesn’t join for a given input, that input's record is supplied with an all-null placeholder.
