I am starting to get into Tableau Prep. I have found that when I tried to change source data (but keep the same downstream flow), I have a few erros and can't fix them.
There are 4 fields that existed in the original data source, and not in the new data. All is good until i get to a pivot step which originally pivoted these values. Since they are no longer part of the data set, PREP throws and error. When i try to go into the Pivot step to 'remove' the errors ('unknown field'), there is no way to 'remove the history' from the pivot? How can i remove them out o fthe pivot names field without breaking the whole flow, removing the pivot, and rebuilding? I was hoping i could drag out the fields.. no luck
In the pic you can see the error... Average direct labor wage ($/FTE) 1 ..........it's remnante of the old data set?
Hi Mark -
Do those extra fields carry over to the Clean step that follows the Pivot?
