I have two tables, table A and Table B. In table A, I am getting Unclassified so I want to get the data from Table B i.e. instead of Unclassified I should get US and when it is United States it should return United States.
I joined a workflow that I feel, only using TableA, would suit your need, retrieving all information from field "Company". Tell me if you'd rather isolate missing data in another table.
