Update a single entry in a Feature Class

JacobHolcombe

I am trying to update a single entry in a feature class with new data from a work order. I have a feature class that contains all of the meter's in within an area. When the crew goes out into the field and change out a part they bring me a work order with the new serial number, model etc. Is there a way in model builder to select the single entry to be modified and update it with these new values? So far the only method I have come up with was to create a new feature class with the Select tool, then using the Calculate Field tool update each field. The problem has been getting this data back into the source feature class. I was trying to avoid a situation where I delete the old record and append the newly created one if possible.

All tools honour a selection, this is basic GIS. So select your row first using the select by attribute tool then run the field calculate tool on the field you want to update. The update will only apply to the selection.

Be aware that if your initial selection fails, for example they have returned an incorrect serial number then when you run the calculate field tool it will overwrite everything as there is no selection and there is NO UNDO for that action.

You should not be exporting, editing and then importing that is simply inefficient.

Suggest you create some test data and explore this approach before you apply it to your operational data.
