How to reference new field if it is DAC Extension

问题:

I have a couple of new fields in Sales Order (Screen ID - SM204505). I have added these fields from customization project > Data Access. Once published this customization project all the new fields are created in SOOrder table.

Now I want to reference these new fields in my Customization Project in Visual Studio to fill some other values (i.e. add some more business logic). For example, there is a custom field called UsrReasonCode added to SOOrder table. And then I want to write some business logic to get this value from SOOrder and fill into some other table (i.e. Document Line item > ReasonCode)

It is working if I create Table Extension but I am not sure how to reference if I add it through DAC Extension. Please suggest.

You can reference extension fields by using extension object like that:

DocExt ext=PXCache<Doc>.GetExtension<DocExt>(doc);

This will get extension object DocExt related to the original Doc object. So you can reference extension fields like ext.UsrField.
