Hi Nishant. Was my response helpful? Needing any more help here?
Hi Tadd, thanks for sharing the details.
I am getting below error while opening the shared workbook.
Error : This file was created by a newer version of Tableau. Please upgrade Tableau to the version (or greater) that the file was saved in.
Version I am using : 10.5.0
Is there any workaround to this problem. I am sorry for bothering you, I am new to tableau. Also, if I am unclear earlier, I want only the forecast line to be dash not the actual.
