I have a project which uses multiple data extracts from the same source using Custom SQL.
Have defined few calculated fields in the project.
Upon doing a data refresh, got the warnings as shown below:
All the calculated fields got renamed to a random name like “Calculation_232342342…” which are no more editable as shown below.
Appreciate any inputs to resolve this problem.
Based on these messages, it looks like the data source has changed, and now contains fields that are named the same as the calculated fields in your viz. This is how Tableau resolves the conflict.
