I am trying to create a relationship class(between line and point feature classess) that should be a composite relationship type and M:N cardinality. However, when the tool run, I am recieving the following error message:
ERROR 160270: The relationship class is incompatible with an existing relationship class.
I couldn't find any acknowledgement or work-around. Does anybody know the cause or the solution?
It seems this is a very rare error message based upon this link. One thing that comes to mind is do you already have a relationship class built upon the line and point feature class and are attempting to build a second on top of the existing relationship class?
Not sure if you are still having trouble with this, but for anyone else who comes across this post while searching this error message, I wanted to share what I found out.
I was receiving this Error 160270 while trying to add a second relationship class for a feature class within an ArcSDE database that already had a composite relationship class with that particular origin table. After doing a little research I found that it was because you can't have more than one composite relationship class with the same origin table. Changing it to a simple relationship class allows it to work.
