You want this to work with just a single vendor selection or multiple? You could create a calculation using a parameter =customer name/id and use this boolean calc on columns shelf. Hide False and then you will just have true, but all the marks are still there. You can add an 'All' to the parameter to show the entire population.
If you attach a workbook, we can help more.
An alternative to the parameter would be to create a table calculation filter. For example LOOKUP(ATTR([VendorName]),0). Use this instead of the vendor name as your filter.
One weakness of this technique is the filter will only apply to the individual worksheet.
I have attached the workbook. The worksheet is labeled as Score/Percentile. It is included on the dashboard. Currently all vendors are listed on the worksheet but I need a way to isolate specific vendors, without filtering the data, so I can publish a report to each vendor.
I am extremely new to parameters so any help would be fantastic.
I can't see your worksheets. You need extract your data when connecting to a server.
Try this though.
Create a parameter for your vendors. If they are strings, select string for the data type and fill from the vendor field.
Then Create a calc like this:
[Vendor] = [Parameter]
Put the field the columns. Right click on False and select Hide. Then Hide the field label for true.
Now all the marks are still in the view, but only the vendor you have selected is visible. You can use the parameters in the titles and stuff too.
Hope that helps. Adam
