Auto Numbering based on 2 columns value.

[bentxoxo]

Hi All,

Can someone please help me on below formula.

I am trying to add +1 if order number and store number (any one) value are different but if both values are same just use above number.

=IF(OR(C3=C2, B3=B2), A2, IF(OR(C3<>C2, B3<>B2), A2+1))

Hi Mohadin, Nishant94,

Thank you for your reply.
@Nishant94, Just a small change if possible! Company name always be there which is column "B" but some time if I don't have PO number. So if PO number column "C" is empty it should add +1 because company name is not matching with the last one. Please see below.
