Hello...
I am trying to identify back orders in a shipment file.
1 A B
2 APPT DATE ORDER
3 1/10/2014 4017970
4 1/14/2014 4018722
5 1/14/2014 4018919
6 1/14/2014 4018975
7 3/12/2014 4019001
8 1/7/2014 4019192
9 1/20/2014 4019253
10 1/14/2014 4019278
11 1/2/2014 4019366
12 1/3/2014 4019482
13 1/6/2014 4019482
14 1/8/2014 4019482
The formula IF(AND(B1=B2,A1<>A2),"BO","") works if the date is different on every shipment. However, if the date in Row A14 is 1/6/2014, the formula will return blank (""). I have tried to use SUMPRODUCT() but the same issue happens.
Any help would be appreciated.
TIA
