Your terms are getting a bit garbled in the posting process as well as what view you are refering to in Navigator and CL. Could you attach a picture of each so it can more easily be displayed? On another note, when using Operations Navigator there is an indicator in the upper right part of the screen which will indicate when the data was collected that you are viewing or if it done dynamically it will indicate how old the data is. For the cases when a date is shown, the data had been collected so searches can be performed against it (i.e. tell what system Joe is on, tell me what system has PTF xxxx on it...). The inventory also lets enables more advanced functions like comparing PTF levels and exporting data to spreadsheets. There are many articles and presentations on the topics as well on the navigator web site (www.ibm.com/eserver/iseries/navigator).
