For creating the classes, look at the below links

<b>difference between BAPI and RFC</b>

BAPI is used only when it is available for the particular transaction like Delivery Sales order. but BDC can be used for any

transaction which have screen and fields.

BAPI is directly updated the database instead BDC run through the screen flow.

So BAPI can't handle all the flow logic checking and enhancement put by programmer to faciliate the user requirement.
