Excel SUMPRODUCT and dynamic text conditions - excel

Question

I am trying to do a summation of rows with certain dynamic conditions. I have rows like:
A can be only one value, K can have multiple OR-values. In the end M is to be summed.
I have tried to use SUMPRODUCT() which works for column A but not for K. What I am looking for is something like:
=SUMPRODUCT(--(!$A$2:$A$20000="AA")*--(!$K$2:$K$20000="AA" OR "BB")*$M$2:$M$20000)
I know I can do ="AA" and then ="BB" but I need "AA" and "BB" to be dynamic based on other cells. And the number of arguments is different. I tried {"AA";"BB"} but I know this will not work as the match then needs to be in the same row.
Can it at all be achieved?
Thanks a lot!

Answer 1

=SUMPRODUCT(($A$2:$A$20000="AA")*(($K$2:$K$20000="AA")+($K$2:$K$20000="BB"))*$M$2:$M$20000)
Note that:
Since you are multiplying/adding arrays, there's no need to include the double unary's
I don't know why you have a ! in your example formula.
To return an OR array of TRUE;FALSE, we add.
Your comments still do not provide a clear explanation of what you are making dynamic.
But to create a dynamic OR for column K, including testing for column A and summing column M, you can do the following:
For column K, let us assume that your possible OR's are entered separately in the range F2:F10
=SUMPRODUCT(MMULT(--($K$2:$K$20000=TRANSPOSE($F$2:$F$10)),--(ROW($F$2:$F$10)>0))*($A$2:$A$20000="AAA")*$M$2:$M$20000)
The matrix multiplication will produce a single column of 19,999 entries which will be a 1 for matches of any of the OR's and 0 if it does not match.
See How to do a row-wise sum in an array formula in Excel?
for information about the MMULT function in this application.
In the above formula, "blanks" in the OR range (F2:F10) will also match blank entries in column K. So it is conceivable that if there is a blank in K and F and a AAA in col A and a value in column M that a wrong result might be returned.
To avoid that possibility, we can use a dynamic formula to size column F where we are entering our OR values:
=INDEX($F$2:$F$10,1):INDEX($F$2:$F$10,COUNTA($F$2:$F$10))
will return only the values in col F that are not blank (assuming no blanks within the column)
So:
=SUMPRODUCT(MMULT(--($K$2:$K$20000=TRANSPOSE(INDEX($F$2:$F$10,1):INDEX($F$2:$F$10,COUNTA($F$2:$F$10)))),--(ROW(INDEX($F$2:$F$10,1):INDEX($F$2:$F$10,COUNTA($F$2:$F$10)))>0))*($A$2:$A$20000="AAA")*$M$2:$M$20000)
Given this data:
the last formula will return a value of 5 (sum of M2,M3,M7)

Answer 2

Use SUMIFS with SUMPRODUCT wrapper:
=SUMPRODUCT(SUMIFS($M$2:$M$20000,$A$2:$A$20000,"AA",$K$2:$K$20000,{"AA","BB"}))
