IF-MIN-SUMIFS function does not give the proper result

MINIS2310 , if you mean to find min date in AP against column C where values match row values from P to V, when it could be (in AQ30)

=AGGREGATE(15,6,1/(C:C=$P30:$V30)/(C:C<>"")*AP:AP,1)

However, performance will be bad on entire columns.

In your locale you need to change commas on semicolons in above formula.
