finding unique items in an excel list -

-

i trying count unique number of entries in pivot table.

my pivot table displayed such:

u       v           w       x           y       z    aa pn#     customer    offer#  date        $       qty  sum of offer# 123456  00000001    157815  09.06.2015  16,3    25   1 123456  00000001    157815  09.06.2015  31      10   1 123456  00000001    157815  09.06.2015  43,5    5    1 123456  00000001    157815  09.06.2015  65,3    1    1 123456  00000002    156682  31.03.2015  10      140  1 123456  00000003    157505  19.05.2015  20      25   1 123456  00000004    156925  13.04.2015  10,04   1000 1 123456  00000004    157459  18.05.2015  9,44    1000 1 123456  00000005    158036  23.06.2015  16,3    25   1 123456  00000006    157064  20.04.2015  10,8    100  1 123456  00000006    157064  20.04.2015  12,5    50   1 123456  00000007    156616  26.03.2015  9,5     700  1 123456  00000007    157264  29.04.2015  9,3     450  1

this list of order offers make customers. want analyse see how offer products etc

so far, have number of total offers using:

=sumproduct(--($u$5:$u$7000=u5),$aa$5:$aa$7000)

this shows 1 article number, how many offers there are. of course, counts duplicates well.

so testing countif:

=sumproduct(1/countif($w$5:$w$45,$w$5:$w$45)) (sample fixed range - goto row 7000)

and works fixed range.

so, question - how combine two? - can see 1 product number pn#... unique number of offers made. can of course use same fomula see unique number of customers, @ present not possible.

thanks!
