to put a button, go to development / windows : select  opoh, add a button to the list, select the right destination (object), validate. There is an order, you need to change the number is necessary. Look at other windows, you will see similar example.

pass the values, no idea.

Thanks. I'd got as far as adding a new button to OPOH object and the action GOBJET with the parameter "PTH" to go to the receipt screen. It doesn't seem to filter down on the order I've got selected though...
