Set default value of a checkbox

Hello there,

In the PurchReqLine details, there is a checkbox for 'Accept partial delivery'. By default this is set to false. How would I modify it to true by default.

I tried setting the value to 1 in AOT but it didn't work.

I also tried inserting a line in the run() method of the main form (PurchReqTable form) methods as: LineComplete.checked(true);

That didn't work either.

Any help is appreciated.

thank you.
