I have parcels that were split in the process of joining them to a subdivision polygon layer. I used the dissolve tool since there was repeats. I used the Property ID to merge them together since this is unique value. The count number reduced dramatically. It creates a new table, but my problem is that it only contains OBJID, shape, Property Id, shape length and area but not all other attributes. I tried to do a join based on property id but the OBJID now has repeats, and the count goes up again from original attribute table.
What did you do during the dissolve to account for attributes?
you may lose attributes during the process that you need to deal with
