Can you dump multiple lines of vertical data into one cell?

I have a worksheet where i want to take all the pick tickets for a p.o and dump them into one cell with a comma separating each of them. I could use an AND formula, but the worksheet is a living document that changes daily and it will be used by someone who's not excel savvy. And more importantly, I want as much of the worksheet as possible to update on its own.

I need a formula in the cell to say "Dump all the pick tickets for a p.o into this cell and separate them with a comma"

I should also note that all of the pick tickets are going down the sheet in case that makes a difference.

I feel like it would be a vlookup and an array formula, but I cannot figure it out.

I've attached an example of what i want it to do. There's 3 tabs, the raw data which is what my pivot table will pull from, the Before Pivot which will show how it currently looks because I can't figure out the formula, and the After Pivot which will show what I want the end result to look like.

If you're saying the values in raw data are ordered by PO# (implied by sample) then:

'Raw Data'!C2
=IF(COUNTIF($A$2:$A2,$A2)=1,$B2,INDEX($C$1:$C1,MATCH($A2,$A$2:$A2))&","&$B2)
copied down

'Raw Data'!E1: Bucket [ie header value]

'Raw Data'!E2:
=LOOKUP($A2,$A$2:$C$20)
copied down

Revise the PT source to include column E and use this in your Pivot (rather than C).

The above means all is formula driven and dynamic though I would reiterate the above is based on assumption that data is sorted by PO#
(ie utilises binary search for optimisation)

Yours kind of makes sense but I can't get it to work. A. How do i run it once it's in there and B, it's giving me a compile error on each line of formula.

I'm not quite sure what you mean by a Compile Error (that's a VBA term) but based on your locale of US the suggestions should work without issue.

In other words, in the actual file, that column is blank and I want all the pick tickets to pull into it.

Not so. The formulae when entered in the cells designated will generate the requested results - attached.

I had presumed that by adding a working example with PT output the below would all be rather transparent, seemingly not.

As mentioned in my first post - the "final" ticket bundle for the given PO is generated in Column E not Column C and the Pivot uses the new column as source (not Col C).

Col C in this approach acts as a "running count" string - nothing more (it is not the final output as used in the Pivot)
That is to say the string extends with each PO transaction as a new ticket is added to the bundle.

Col E subsequently references the last "running count" string in Col C for the given PO thereby ensuring that all transactions for any given PO use the final complete ticket bundle string for that PO.

Given Col E now holds the final bundle string for the PO we use this in the Pivot.

The reason we use 2 columns [Col C & E] for this formula driven approach is efficiency.
