The Freeze level tab contains only one UI element: the Freeze level text box. This text box specifies at which level of signoff the relevant Portfolio instances will be frozen. Three levels of signoff are generally used, thus you are expected to type ‘1’, ‘2’, or ‘3’ (the last level). In addition, you can leave ‘0’ – in this case, the signoff level value will be inherited from the underlying DataModel objects. 

For more information about the Signoff and other relevant processes, see the “Enterprise Report Submission Help” document.
