Collection After update Metadata

Hi All ,

I am using framework folder after checkin document .so chedckin is workingfine as expected .

Now while updating metadata from Update_DocInfo page , newfolder should get created and that document should checkin inside newly created folder .

for eg : I have two metadata fields : State and city

If metadata value for city is updated from Illinois to heisenberg .

Document should checkin under heisenberg (New folder) .

what approach I should follow ?
