Syntax

GROUPMAP(<any>; <any>)

Description

Creates a JSON map based on two columns of all records within a group, keys, and values.

This is an aggregate function. 

Example

Given the following data:

Then use the GROUPMAP(#RawData!Item;#RawData!Customer_), and the result is a JSON map based on your two column records in relation to the GROUPBY() column.
