I need to apply Close Functionality for user Defined forms . As ,when we close any System form like Sales Order then we can not update any thing on that form ,same functionality i need for my customized form. I have tried Close option available in data menu of SAP B1 which is working i.e. means when i close my form using this option then in database the value of Status field of that table is changed from O to C . But still we can update the things in the form.
Please help me .
