Updating Value of an atribut

SebastianEnnenga

Hey,

I have a Point feature class and I want to update the value of an atribut with an value of the same atribut in a table. I need something which works within the modelbuilder. I tried "join field" , but it is always adding the atribut instead of updating it.

A join in ArcGIS Pro would work IF you have a common field between the point feature class and the non-spatial attribute table. Once the join is created, then you can do a Field Calculation from the table to the point feature class attribute table.

Hi,

I tried that allready. Check out the picture. Maybe I did something wrong?

That is the error I receive.

Right. So two things I see is the GP tool says you have pending edits. You'll have to save or discard edits first as this is a schema lock on tables. Second, your Expression is incorrect. You do not need to have an equal sign on the leading part of the expression. Clear this whole line and double click on the Anzahl_Nachbarn field. This will populate the expression for you with the correct syntax.

Ok, I saved everything ,delete the eqal sign and just doubleklick on "Anzahl_Nachbarn". Now I got this error:
