The dialog can be integrated in the process in many ways. This is ideally solved by a button close to the subtable. The order assignment starts by calling the function fSelectOrderItems().
Optionally the parameter true can be committed. By calling fSelectOrderItems(true) the already assigned data (and possibly edited data) are used after a re-start of the order assignment, instead of using the raw data of the order.
To customize search boxes see filter, in fields.xml.
