Hi @Priya Jha ,

Thanks for using Microsoft Q&A forum and posting your query.

You can use mapping data flow expression builder to achieve your requirement. You can utilize combination of mapIndex function and map function as below:


mapIndex([1,2,3,4,5,6], iif(#index == 3, map([1,2,3,4,5,6], #item)[4], iif(#index == 4, map([1,2,3,4,5,6], #item)[3], #item)))
