The matching-pattern capability is configured in an Input step in Tableau Prep Builder. When connecting to file-based data such as text files or Excel files, Tableau Prep can include multiple files and create an input union by using wildcard or matching-pattern criteria. This allows similarly named files to be combined into a single table as they are brought into the flow. A separate Union step combines already-added tables or inputs, but the question specifically asks where a single table can be created from a matching pattern of multiple file names. Join combines tables based on key fields, while New Rows generates missing sequential records. Because wildcard file matching is part of the file-ingestion configuration, Input is the correct step.
