Hi @charlesbanks,
I believe that you can compare these values ( if has a not unique ids ) with a temporary data, for example Excel file using the transformer FeatureWriter. After a transformer Tester to compare the Ids from you Reader ( Input ) and your temporary XLS.
Thanks,

fid in shapes are just like row numbers. Delete a row and all is reset.
Generating unique id's from those will only be valid as long as you don't rerun the generation based on these fid's.
If you want to partition your data based on attributes, create a group by attribute based on the required attributes. Usually by concatenation.
GroupBy= @Value(pt) @Value(rt ) @Value(st) @Value(etc.)
Or if string is getting bit long, by using a counter to id each attribute and create Group By of those values
Use the group by value in a counter.
