I always wondered why ArcGIS doesn't have an option to concatenate text fields when using dissolve tool. This image is taken from another discussion:
The solution given at this discussion was a Spatial Join Tool and using field mapping. But the result was not as anticipated. It repeats every field value over and over, eventually fails because of field size.
It would be logical to have option in the Dissolve tool and using field mapping. Currently there is field mapping option but that is only for numbers.
I'm searching for the same problem at the moment.
I have different points with text that muyst be dissolved to the polygon.
Did you find the solution?
It is possible to dissolve and then concatenate those fields. For the Statistic Type choose Concatenate then you are able to specify the Concatenation Separator in my example I chose a semicolon. For the field you are concatenation you may also need to set up the Merge Rule too.
However, I would like to concatenate the last entered note as the first in the concatenation string so that's where I am having an issue.
Hope that helps!
