We have the same issue on one workbooks when the incremental refresh extract running on the server side.
Did anyone have the same issue? somebody resolve it?
this is the error:
com.tableausoftware.vizql.dll.TableauException: Tableau Data Engine Error: 4: Scan::Next: Mismatched row counts The table "[Extract].[Extract]" does not exist. Unable to connect to the server "xx.xxx.xxx.xx". Check that the server is running and that you have access privileges to the requested database. Errors occurred while trying to load the workbook "saletest/extract". The load was not able to complete successfully.
