Hello,

This is me again. I will need your help again to design me macro which can
give me output as below.

I have huge excel file, which includes around 6000 lines. In column E I have
"TPDoc Number" & Column F I have "Shipment number" which are similar to TP
doc no most of the time.

In column N I have "Date/Time". I want you to design macro which can give me
difference between all dates for the same bill no... (I.e. How many days did
we took to complete task for specific bills) & please keep in mind there one
TP Doc number can have 4, 5, 6 and so on different lines. See beloe example :
Column E Column F Column N
Column O
