Multi Row/Field Formula For Finding Largest Value Over A Specific Type

[jlrouquette]

Howdy Community,

I'm looking for help with a multi something formula, or whatever works best, to identify the largest value for a specific pad.  Every pad has several wells and every well has several events.  Some events will be null.  The number of wells per pad, and events per well can change but I need to identify the largest value per pad regardless of those inconsistencies.  

I've attached an example dataset and shown a simple example below.  In the example below the "Large" category represents the output I'm looking for from a formula.  The other 4 columns are those that are available to me.   

WELL	Pad	Event	Value	Large
Well 01	Pad 1	Event 1	7.5	YES
Well 01	Pad 1	Event 2		NO
Well 01	Pad 1	Event 3	1	NO
Well 02	Pad 1	Event 1	2	NO
Well 02	Pad 1	Event 2		NO
Well 02	Pad 1	Event 3	1	NO
Well 01	Pad 2	Event 1	6	NO
Well 01	Pad 2	Event 2	3	NO
Well 02	Pad 2	Event 1		NO
Well 02	Pad 2	Event 2	9	YES
Well 02	Pad 2	Event 3	1	NO

Any assistance would be much appreciated!

Hey @jlrouquette 

The summarize tool would be the tool here 🙂

Group by Pad, Max of Value, then you can rejoin this back to get your original data to get your "large" flag

Hi @jlrouquette 

Here's a solution:

- Find the Max value per pad using Summarize Tool

- Left Join this max value to the original dataset

- Use formula tool to apply "YES" or "NO" condition

- Organize your dataset again by sorting by a Record ID

At the end I validated the desired output and it matched.

WF attached.

Neil, that is exactly what I was thinking, you beat me to the punch!

Attached is the workflow

Hi @jlrouquette 

Couple of ways, you can do it in a multi-row formula like you say (of which there's many approaches within it you could take in the formula)

Or like @LordNeilLord says, you can use a summarise.

Both options included as examples here... 

Be mindful of whether you want the solution to name just the first instance of the largest number as "YES", or all of them (e.g. if you had several all with the value 33.5 in pad 1) - either option is doable; see attached workflow
