Top N with What If Parameter

Hello,

I am currently using TOP N with What If parameter to rank Revenue by Company Names, it is working fine but there maybe cases where Company Names maybe same and in such scenarios, the revenue will get summed for those company names. If I use "Company Key" to rank, I can no longer use Company names on the Axis of the bar graph. It shows a "ran out of memory exception". How do I handle this in Power BI?

Thanks in advance.
