Is there a way to filter and return results for the unique of one column, with conditions of another? - filter

Question

Question
For the data below, is there a way to return results —for each order in col B— either:
If the most recent status [col D] for an order (ex. for order 10021) is closed, then return that row.
If not, return every row since the most recent closed status for that order (ex. for order 10020, rows 4 and 5).
Previous efforts and attempted solutions
Previously, I was only returning one result, the most recent status for each order with the following:
=SORTN(SORT(A2:D,1,FALSE),9^9,2,2,FALSE)
However, I would like if orders can have more than one current status.
I've tried a few things, and was able to achieve what I'm looking for, unfortunately only if there is one order, with the following:
(The linked sheet below explains how I got to this)
=IFERROR(FILTER(A2:D5,A2:A5>INDEX(SORT(FILTER(A2:D5,D2:D5="CLOSED"),1,0),1,1)),FILTER(A2:D5,A2:A5>=INDEX(SORT(FILTER(A2:D5,D2:D5="CLOSED"),1,0),1,1)))
The other alternative I can think of is a script with a loop.
Summary
It was difficult to know how to title this question but came to it since essentially we're trying to filter for the unique of col B, with conditions against col A & D.
Here's a link to a sample Google spreadsheet you can edit, showing all the attempts.
All your help and comments are greatly appreciated!

Answer 1

maybe like this:
=ARRAYFORMULA(UNIQUE(SORT({VLOOKUP(UNIQUE(INDIRECT("B2:B"&COUNTA(B2:B)+1)),
SORT({B2:B, TO_TEXT(A2:D)}, 2, 0), {2, 3, 4, 5}, 0);
FILTER(A2:D, D2:D="RETURN")},1,1)))

Answer 2

Solution
All credit to Matt King who found a complete answer.
=ARRAYFORMULA(QUERY({A:D,(COUNTIFS(C:C,C:C,A:A,">="&A:A)=1)*(D:D="CLOSED")
+NOT(REGEXMATCH(TRIM(TRANSPOSE(QUERY(IF((TRANSPOSE(A:A)<=A:A)*(TRANSPOSE(C:C)=C:C),D:D,)
,,9^99))),"CLOSED"))},"select Col1,Col2,Col3,Col4 where Col5=1"))
Essentially,
First assigning a count to each row for any given order
Transpose and combine statuses
If there is a CLOSED status in there, don't use it
Then filter with query language
Resulting in—
See solution here.
Mod
I added a clause to completely exclude the status NOTE from current records—
=ARRAYFORMULA(QUERY({A:D,(COUNTIFS(B:B,B:B,A:A,">="&A:A)=1)*(D:D="CLOSED")+
(ARRAYFORMULA(IF((ARRAYFORMULA(NOT(REGEXMATCH(TRIM(TRANSPOSE(QUERY
(IF((TRANSPOSE(A:A)<=A:A)*(TRANSPOSE(B:B)=B:B),D:D,),,9^99))),"CLOSED"))))
=TRUE,IF((ARRAYFORMULA(NOT(TRANSPOSE(ARRAYFORMULA(TRANSPOSE(D:D)))="NOTE")))
=FALSE,FALSE,TRUE),FALSE)))},"select Col1,Col2,Col3,Col4 where Col5=1"))
Implementation
This was sample tested against 2500 rows of data, and took over 80 seconds to execute. So although this answers the question, it isn't necessarily a viable solution.
