Finding Max value from a column based on a criteria on other column

[hemantparmar]

I have sales data for multiple years in a table. The estimate ref numbers in this table are serial numbers like 1, 2, 3 and so on. Every year this number restarts at value 1.

I need to give a reference number for a new estimate which is one more than the max estimate number prevailing for the year chosen.

At the moment I use the below method. Please let me know if there is a better option.

I use Advanced Filter Copy method and paste the filtered table for the required year in a new sheet and then find the max number from the estimate column.

Any better idea that does not involve creating another temp sheet. In excel I would use Aggregate function. But I am not sure how to write that statement in VBE.

Please attach a sample workbook (not a picture or pasted copy). Make sure there is just enough data to demonstrate your need. Include a BEFORE sheet and an AFTER sheet in the workbook if needed to show the process you're trying to complete or automate. Make sure your desired results are shown, mock them up manually if necessary.

Remember to desensitize the data.
