I created a worksheet using the sumproduct formula and it runs very slow.
15-25 minutes to calculate at every change. I guess its to big for my
computer to run ( the worksheet has 248 columns and 100 rows of formula)
Can I speed it up somehow? Or can I get I get match to do multipe criteria?

=SUMPRODUCT(--('A-L Data Table'!A$6:A$2496=$A10)*--('A-L Data
Table'!B$6:B$2496=$D3),'A-L Data Table'!$D$6:$D$2496)

Maybe something like =INDEX('A-L Data Table'!D$6:D$2500,MATCH($A10,'A-L Data
Table'!$A$6:$A$2500,0)*MATCH($D$3,'A-L Data Table'!$B$6:$B$2500,0),1)


Thanks,

Hi
a formula approach probably won't help you in this case. You may try using a
pivot table instead

You might want to invoke a SumIf formula instead...

Insert a new sheet that you could name Concat...

In A6 on Concat enter & copy down:

='A-L Data Table'!A$6&","&'A-L Data Table'!B$6

Then invoke:

=SUMIF(Concat!A$6:A$2496,$A10&","&$D3,'A-L Data Table'!$D$6:$D$2496)

This set up trades off cell space (memory) against speed (time).

Another option is to build an appropriate pivot table from your data.

Thank you all, very much you were very helpful as always.
