Maybe sort the collection by roll number (there is an action for this in the utility collection VBO) and then loop through it saving all items into a seperate collection as I go until the roll number changes - then do what you need to do - then continue looping storing the items with the next roll number.

Yes, I have sorted the collection. How do I stop until I see a new roll number? anyway for me to ""get next item and then check if previous value of roll no equals current value"" (if this bit I can get some advice), then I know how to proceed , if so, then add row to collection, else stop
