I'm new to Tableau and would like some inputs on the below situation.
I have 2 datasources
Datasource1 which has EmployeeId as the key
Datadource2 which has a column Employee- which is EmployeeId followed by EmployeeName(no spaces between).
For me to join Datasource1 to Datasource 2 ,on EmployeeId, I would need to first create a CalcEmployeeId(using Left(Employee,5)).
and then make a join of Datasource1.EmployeeId to Datasource2.CalcEmployeeId
But Birst doesnt seem to allow this, Please advise how do I go about joining Datsource 1 and Datasource2 by Employee Id?
Appreciate any thoughts on this.
Providing sample data or a sample packaged workbook will make you much more likely to receive a response.
