OMNF (Requirement Types for Whse Mgmt) is a standard SAP parameter transaction code that is used to maintain the contents of V_T308 database table. It does this by executing the table maintenance t-code SM30 in edit mode, assuming you have the appropriate authorisations.
In-order to use this transaction within your SAP system simply enter it into the command input box located in the top left hand corner and press enter. Here are a few additional command options available to use when doing this.
GUI Support Inherits GUI attributes from  SM30
SAPGUI for HTML The SAP GUI for HTML generates HTML pages for every SAP screen. This means that you do not have to create any templates. There are however some technical restrictions due to the browser and certain transactions may not function in the SAP GUI for HTML.
SAPGUI for Java SAP GUI for Java is a plug-in, a program downloaded from the browser to the PC and executed there. This GUI version supports more controls than the SAP GUI for HTML, but you should still test the transaction. It also requires users to download and install the client on their PC so the Java GUI is the second choice after the SAP GUI for HTML.
SAPGUI for windows Transactions can also be run under SAP GUI for Windows. It must be flagged with SAPgui for Windows (previously known as WinGUI).
