I'm using the output sharepoint to an excel file that has a tab with a pivot table and graph. But when I run the workflow, it adds my data from the workflow (as expected) but changes my pivot table to "just data" and erases the graph.
I don't have this problem when I output to an excel file in my desktop.
I'm just starting to use output to sharepoint files and not sure if I'm missing something in the configuration of the output sharepoint file.
