    Merge mismatched fields in the union, breaks existing field filters

    Guy Glossop

      Hi

       

      I'm on Version 10.2. I have a fairly complex workbook that works for a sample data set but when i use Union and merge fields to expand the data set i get a series of error messages and issues relating to the merged fields. I have tried renaming the merged fields to the original name but it seems that on creating the merged field Tableau also generates a new field in the data source tab that coresponds to the original field name.

       

      Any suggestions? Also is this the best practice expected behaviour when performing such a merge and if so why?

      UPDATE: I resolved the issue by editing the headers of the Data source CSV files to all be consistant but i'd still lke to know if there is a way to do it without taking that approach
