I am having 3 datasets (a main report - JDBC connection and 3 other datasets - same connection with the main report), in which they have a common field, called file_reference_number. I want to use the field "file_reference_number" as a parameter, so that other datasets will show data only when matched cases. How do I achieve that? e.g. Dataset 1 has 3 fields: name, address, file_reference_number Dataset 2 has 2 fields: contact_info, file_reference_number Dataset 3 has 3 fields: descriptions, title, file_reference_number I am not sure how to "lined up" the file_reference_number at the same time. Should I use a parameter map, maybe a non-prompting parameter or some sort of filter expressions? Thanks everyone in advance
