Each row is unique so there is no need to account for duplicates. This is what I'm trying to achieve: data want; input customerID product count; datalines; A1 P4 3 A1 P6 3 A1 P2 3 A2 P3 2 A2 P4 2 A3 P1 1 ;0 Like

This will give a performance boost at the expense of counting files with identical contents multiple times (if such duplicates exist). --stat Some file systems (AFS, CD-ROM, FAT, HPFS, SMB) do not have directory 'nlink' counts that match the number of its subdirectories. Consequently cloc...

have unique values for ID in both datasets? If so, the easiest way to check for duplicates is to add a logical assertion your MERGE step, e.g.: data merged_dataset; merge dataset1 dataset2; by ID; if NOT (first.ID and last.ID) then put "ERROR: found a duplicate! " ID= ; run...

There are no duplicates within any variable, but many duplicates across.Those shared values between variables are expected and I do not want to eliminate them.Some variables have many missings.For any of those datasets, I want a count of the number of values that are identical in combi...

If you do have duplicates then you need a count distinct, here's examples (that you can copy and fully run) that illustrate how to do a distinct count per group. https://github.com/statgeek/SAS-Tutorials/blob/master/count_distinct_by_group.sas @wlierman wrote: I have a SAS Dataset ...
