Hi Lewis
Unfortunately, no, that doesn't help. What I need to be able to do is:
Select documents based on a due date cutoff - yes, can do.
Select the range of vendors I want included - yes, can do.
Select the range of documents within those vendors and within the due date that I want included - no you can't do this - unless the selection criteria is based on Global Dimension 1, Global Dimension 2, Date or Currency.
Essentially, it is needing to extend the options available under "Filter Totals By".
Cheers
Heather
