I am going to be using an AddJoin_management command in a python script at the end of several loops. To test, I used the AddJoin tool and use the below command in the Python window and made the parameters identical to what the code is(the parameters are correct for what I want to accomplish). When I run the AddJoin it crunches numbers for a while and then the whole program crashes and asks if I would like to send an error report.
arcpy.AddJoin_management("SignsToFinish", "SignID", "NewSigns", "sid", "KEEP_ALL")
That is the statement that is being used in both the script and in the AddJoin tool.
Why does this cause ArcMap to crash? Any ideas?
