QA Build will generate field processing automatically for all the database fields set up on the main map. Select the Generate Field Processing option on the Field Processing tab. This saves you the effort of specifying each field individually. It also ensures that all the fields you placed on the map are set up.
You may still add additional processing, for example, for initialising and validating a field.
You should check the field processing that the Program Editor generates; inevitably it sometimes has to "guess" the required options, based on program type and procedure type. For example, it may set up a field as an input field, although the user should not be allowed to input data there.
