Option 1Add matching values to the linking fields in both tables in the data source.
Option 2Rearrange tables in the join.
The table that contains all possible values in the linking field should be the leftmost table in the join when the join type is Left Outer Join. If neither table contains all possible values, this option will not work.
Option 3Use a Full Outer join.
A Full Outer Join will include all records from both tables even when there is no matching values in the linking fields. Please note, data for which there were no matching values in the linking fields will not be related. Also note, the Full Outer join type is not available for all data sources.
CauseSome join types exclude data when there are no matching values in the linking fields. To learn more about how table joins work, please see Join Your Data
