I have a workbook (B) that uses a Tableau data extract file (.tde) as it's data source. The tde was created from workbook (A). I have created many calculated fields in workbook B and some in workbook A. I believe I resaved the data source for workbook A and now I have two calculated fields in workbood B that start with "Calculation_NNNNNNNNNNNNNNNN" (i.e., 16 digits) that I cannot edit or delete. I can duplicate it and it allows me to edit or delete the copy. When I edit the copy, the formulat just shows the name of the calcuated field. (e.g., "Calculation_NNNNNNNNNNNNNNNN").
Any thoughts on how to edit or delete these calculated fields.
