I have added a new field to table QMEL, adn this field links to a 'Z' table. So I have created a domain poiting to this table, and a search help whihc passes in the customer number, and then passes back the value for my new field, based on what is held in the 'Z' table. This all works fine.
But then I have aded the new field to the IW51 transaction, and when using the search help in the transaction, the trasaction just returns the full list of options. So how can I get the transaction to pass in the customer number, so that it restrcits the returned list.
