Dear community,
I would like to ask how do we build the formula below :
1. If the " Tracking Number column" showing the same number wih the following row and the "month column" showing same number with the following rows , then we give remark as "yes" for the first row under the " Check column" and give remarks as " No" for the followng row under the "Check column"
2.If the " Tracking Number column" showing the same number wih the following row but there is missing detail "month column" , then we give remark as "yes" under the " Check column" for the row containing detail and give remarks as " No"
for the row that does not have the detail.
3.If the " Tracking Number column" showing the different number wih the following row and there is missing detail "month column" , then we give remark as "no" under the " Check column".

Thank you.
