Used to edit the Active Entity.
If Forms is set to Text Screen in the Database dialog, the edit screen specified in the form table is used for editing. If an edit form is not specified or if Forms is set to None, an error message is displayed.
Note: Depending on the Linkage Mode, editing the Active Entity can change a row in the database. If Linkage Mode is set to New, the Active Entity is a prototype record; editing the Active Entity does not affect any rows. However, if Linkage Mode is not set to New, editing the Active Entity changes the corresponding row. Linkage Mode is set in the Database dialog.
