I have a list of supplier arrears and need a count of total part arrears, but I only want to count a suppliers' oldest arrear.
Supplier | Part | August | September | October |
---|---|---|---|---|
A | 12345 | 1 | 10 | 0 |
A | 12346 | 0 | 5 | 0 |
Desired Count | 1 | 1 | 0 |
I have tried countif on the columns but do not know how to exclude the newer arrears from the count.
Please try
=LET(range,$C2:$E3,
minCol,BYROW(range,LAMBDA(row,MIN(IF(row>0,COLUMN(row))))),
SUM((C2:C3>0)*(COLUMN(C2:C3)<=minCol)))
in C4 and pulled across
or this should spill:
=LET(range,$C2:$E3,
minCol,BYROW(range,LAMBDA(row,MIN(IF(row>0,COLUMN(row))))),
BYCOL(range,LAMBDA(col,SUM((COLUMN(col)<=minCol)*(col>0)))))
