I have one main shapefile with many various attributes. It does include an ObjectID to act as the basis for a join/merge. This shapefile was distributed out to multiple people, who each worked on specific attributes within that file. The attributes all started out with a value of NULL before being distributed.
I am now working on creating a Modelbuilder tool using an iterator to go through these tables and add the new data from each person back into the original shapefile.
I need the new data to overwrite the NULL values for each attribute. I don't have experience with Python and I am fairly new to Modelbuilder as well.
I am currently using 'Iterate Feature Classes' in combination with 'Join Fields', but so far it's not working out. Here's what I have right now:
I have that nested in another model that calculates fields, but my problem lies here and I don't think it will be necessary to nest anyways.
What is the best way to go about this?
