Hello,
I wanted to perform a Grouping Analysis in ArcGIS 10.1. When opening the analysis tool and trying to select a unique ID field the entries where all blanck. I therefore thought, that mayber the unique identifier field wasn't set. Searching the Arc GIS Help Ressources I found this site that tries to explain how to set the Unique Identifier.
When trying to follow the suggested steps i couldn't set the field because after opening the "source-tab" I could not find anything similar to the mentioned "Change Query" field. The only thing I found is the "set data source" field.
Afterwards i checked all the fields in the table and I found the "FID" in the first collumn. Isn't this field thought to be such a Unique ID field?
Can anyone help me how to manually set this field so I can perform the grouping analysis.
Thx in advance!
Best,
Johannes
Hi Johannes
More than a year later, but I'm having the same problem and suspect I'm doing something silly. Did you ever resolve this issue, and if so, how?
Thanks

This was asked long ago, but I just ran across the same problem. My fix is very roundabout, but it did work. It only works for point feature classes and assumes that you want to use sequential integers starting at 1, but just in a different order than the ObjectID you have already.
After I did this I had a new point feature class with the ObjectID exactly in the order I wanted to use. I hope this helps someone else.
