In reply to Stephen Foerster.

Thanks for your reply again! Since We are working on improve our customer's VA report performance on Viya and we have not found the way yet. Our customer's VA reports are full of filter object and list table,which means they didn't use the chart you mentioned before. Not sure if it wold be helpful for the VA report performance improvement, so would it be also helpful for filter object on VA report with the partition key?
Thanks!
