Adding new field to VendInvoiceInfoTable

Hi All,

I added a new field to VendInvoiceInfoTable. I try to edit from VendInvoiceInfoListPage. VendEditInvoice form runs. I update my field, save and exit. Edit again and I see my update dispappeared.

I checked recid fields and vendinvoiceinfotable before edit and after edit, see recid fields are different. I think when push edit button, Axapta copy VendInvoiceInfoTable record to another with skip my field... How can I make edit button run without skip my field?
