Primary Key - Can't update a Record in a grid

unknown

Hello, 

I have a primary key of a table that is comprised of Column1, column2, column 3, and column 4. 

I make an IDO of it. The properties are set to required of course, but not read-only. 

Then I make a grid on a form tied to that IDO. The grid properties are not read only. 

I'm able to create a record and save it. I'd like to update one of the records but it is acting like it is read-only. Is this because it is apart of the primary key? Why would not be able to update the record like you could in a SQL Table? 

Thanks

Hi. Yes that behavoir it is due to the primary key that you choose. And yes. it is very different to update a record using an IDO if you compare the same task if you done using SQL.
