Thanks for your recommendation unfortunately it is unhelpful for my usage because of the usage of Conditional Rankings in the BEx Query. I have already gone down that path and it is not possible. (Query as InfoProvider - Business Intelligence - SAP Library) - For sake of simplicity I left that detail out of my original question however this detail does negate your recommendation.
Conditional rankings is a requirement (I am applying a top 20 customer bottom 10 item (of each top 20 customer) ranking. EasyQuery however does honor and retain the condition, which is why I focused on that.
Thanks, anyway.
