In most Oracle Applications, you can open multiple windows from the Navigator window without closing the window you already have open. HRMS, however, does not support Multiform functionality.
Attention: You must disable this feature on menu structures that accesses Oracle HRMS windows.
Add a Function type menu entry to the top-level menu referenced by your new responsibility.
Select the function whose User Function Name and Function Name are:
Navigator: Disable Multiform
FND_FNDSCSGN_DISABLE_MULTIFORM
Save your changes.
