Update on my Patient Pathway Analysis work for NHS England RightCare.

This is a follow-up to the last tutorial. Thanks to reddit user /u/small_trunks for noticing my blunder! Unfortunately, 'SUMIFS' couldn't be used on its own to create the dynamic data tables. But don't fret! I have another solution up my sleeve that doesn't rely on volatile functions like 'INDIRECT' and 'OFFSET'!

Due to the volatility of the INDIRECT function, it may be necessary to avoid using it when trying to create large dashboards which will be handling and outputting large amounts of data. So, we’ll need an alternative in these cases. One of the ways this can be … Continue reading HOW TO… Excel: Using SUMIFS to Create a Dynamic Data Table
