The message "error occurred retrieving child nodes: Object referenced not set to an instance of an object", is on a data set from PowerBI that I created by merging a table of cash received with a customer master. My need to merge is to use the hierarchy in the customer master as a parameter in Report Builder.
How do I get full access to this merged data set in Report Builder?
Hi @KurtM
You can use cascaded parameters in the report builder to achieve the level of the hierarchy.
