Multi-Row Formula to "copy up" values?

I have a workflow that uses a multi-row formula to "copy down" values but I have a new data set that requires the values to "copy up". I've been playing around with the formula but can't quite get it to work.

Formula:

IIF(isnull([Field1]),[Row-1:Field1],[Field1])

Sample Data:

Field1	Desired Output
[null]	A
[null]	A
[null]	A
A	A
[null]	B
[null]	B
[null]	B
B	B

Easiest method is probably to assign a RecordID to each row, then Sort your data Descending, then use Multi-Row tool to fill down values, then re-Sort data Ascending to put it back in the right order... let us know if that does the trick!

Hi @ddiesel

I would use a record ID to sort so that you can fill down and then resort the data back to its original form.

Let me know if that helps!

Due to the way the Multi-Row tool works it still scans down the data but just reads one record ahead.

The best way I have found to do this is to use a RecordID column and to reverse the order of the dataset. Do the Multi Row imputing and then reverse.

Wow!!! Many thanks to you all for the fast reply! I was able to complete the analysis while still on the phone with the requester! Needless to say, they were very impressed! Thank you!

You don't know what you don't know until you need to know 🙂
Almost 18 months of using Alteryx, I didn't need a solution to this exact problem and I reached the same place as in the original question and was stumped. This did the trick, thank you guys. Now I know a bit more.
