Hello Adi Narayan,

I think you can make you of 'Obj-Sort' method.

Once review more information about this method from the below URL.

https://pdn.pega.com/sites/pdn.pega.com/files/help_v731/procomhelpmain.htm#methods/obj-sort/obj-sort.htm

Here you can specify one or more properties to sort on, and whether the sort sequence is ascending or descending for each sort level.

So if you just want to flip the records then if you have property in the pagelist that holds the index(page no.), then you can use this as basis for sorting.

Thanks!
