    Fields Used in Reports Change After Data Source is Re-published

    simon harvey



      Over the past few weeks we've updated a few datasources, these are all extracts that sit on Tableau server and refresh daily. One of the datasources has a new filed adding, and one had the destination of the source data changed (from view in SQL server to a view in Vertica).


      We have seen calculations breaking in a number of reports linked to these data sources.  When we open the report we see that random elements of some calculations have been replaced either by, in one case the newly added field, and in another case fields nave been replaced by pre-existing fields.


      In all cases by simply opening the broken calculation and replacing the changed fields has solved the problem.


      Has anyone else experienced this? If so is there anything we can do to mitigate this happening?
