I am using an advanced filter to copy a list and then using the DSUM
function to sum all the appropriate fields I would like. However, I
believe there is a problem with the DSUM function as I am using it.
The data looks similar to the sample data below. The probelm occurs
when there are two fields similar to each other, such as "ABC123" and
"ABC123D" which appear separate on the list using advanced filter, but
the after checking the data, the amounts for "ABC123D" are included in
"ABC123". If there is a way for the DSUM function, or another function
to read exact variables, and not so inclusive, that is what I am
looking for. There are more than one occurrence of this problem, so I
cannot list it out individually (i.e, "ABC123" & "ABC123D" also
"DEF123" & "DEF123S") since there are over a dozen cases in my file.
If there is a better way to do this without using a pivot table,
please let me know, any help is greatly appreciated.
