Formula to find the the highest sum of a consecutive list of data

MCODY

I need help trying to figure out a formula that will find the max consumption qty of a particular item on a given day. The tricky part is that there are multiple instances per day of consumption for each item.

It would need to to understand that each day is also a unique identifier and sum accordingly per item.

Are you able to provide screenshots for context? I'm thinking you'll most likely end up with a MAX/COLLECT but want to be sure.

The above picture shows an instance where consumption occurred more than one time of the same SKU on the same day. I need the formula to find the max summed consumption of a SKU each day that automatically updates as we continue to operate.

Paul Newcome

In that case you do need a MAX/COLLECT. Assuming the formula is going on a different sheet, it would look something like this:

=MAX(COLLECT({Consumption Column}, {Created Date Column}, DATEONLY(@cell) = DATE(yyyy, mm, dd)))

MCODY

DATEONLY(@cell) = DATE(yyyy, mm, dd) would I need to choose a specific date to calculate from or would it continuously search for the max summed consumption?

Paul Newcome

You would need to chose a date. You can create a table and have multiple dates listed in a column then use a cell reference if needed.

MCODY

Could I make it a date range?

Paul Newcome

Yes. The criteria would look more like this (same thing goes for the DATE functions as before).

=MAX(COLLECT({Consumption Column}, {Created Date Column}, AND(DATEONLY(@cell) >= DATE(yyyy, mm, dd), DATEONLY(@cell) <= DATE(yyyy, mm, dd))))

MCODY

I tried utilizing this formula to satisfy the equation. However, I am getting an invalid operation. Is the issue DATEONLY(@cell) being replaced by a column reference to another sheet? If so how do I rectify this?

=MAX(COLLECT({Inventory Manager QTY}, {Inventory Manager SKU #}, SKU@row, AND(DATEONLY({Inventory Manager Created Date}) >= DATE(2023, 1, 1), DATEONLY({Inventory Manager Created Date}) <= DATE(2023, 12, 31))))

Paul Newcome

Yes. You need to leave it as @cell.

MCODY

What does the @cell refer to? Should it be referencing something in my Inventory Master Sheet (where the calc is being performed) or the Inventory Manager (where the data is being collected)?

Paul Newcome

No. You just leave "@cell" exactly how and where it is.

It basically tells the formula to evaluate the previously established range on a cell by cell basis.
