ResolutionCreate two separate nodes - one for each branch - or do not use custom SQL.
CauseWhen custom SQL is used and then a self-join from one node after an aggregate step on the custom SQL path to another node on the same custom SQL path, this can happen. Tableau Prep can only have one custom SQL query associated with each node, but the branching path is thought of as two separate SQL queries to the same data source connection. Use two distinct starting nodes if you plan to do a self-join.
