Rule for Sankey Chart

What is the rule to create a sankey chart?

Hi @nivethitha.ponnambal, a Sankey chart must have at least 2 dimension columns and 1 metric column, according to the rule. There may be more than one dimension column, but there should only be one metric.
Additionally, a flag column or date column will be considered as a dimension.

Customer, Product, Revenue

The below query has a flag value in it and it is also considered as a dimension.
Customer , Product , Place , Delivered , Ordered qty
