Change Find button Behavior

Hi,

I've created two User Defined Tables (UDT):

@OITMAD - A Document UDT

@OITMA - The lines of the document

I've then registered @OITMAD using the "Objects Registration Wizard" and I've set the @OITMA as it's Document Lines Table.

Then, using the SDK I've created a Choose From List (CFL) that searches my UDO, and if i create a button and give it the CFL ID, it works.

My question is: Can i change the behavior of the Find button (ID 1) of a System form to search my UDO? I'm using a system form because a lot of the necessary components that I needed were already created in the form I'm modifying.

Thanks in advance!
