The possible solution I could think is aliasing the ids with employee name. But am not sure how you can do this since you have a huge DB. If you navigate to Data--><Select your Datasource>--> Edit Alias--> < Select col name in this case employee id>. Here you can alias the id with name and the names will be displayed in the filter, but the query will have the actual ID instead of names.
I am not sure how u will alias the huge number of emp id in tableau. May be can use a ruby scripting or something.
I have the same issue, and the previous answer does not help as I have too many values to create aliases manually.
Is there a new solution ?
Thanks in advance,
