Hello @sravan,

In order to achieve the wanted transformations you can use two Mapper Snaps.

The first one with Mapping Root set to $cover[*] and mapping the elements of the cover array.

And the second Mapper to rename the cover array to ppCover.

Also, here is a sample pipeline:

Try this out, and let me know if this helps you.

Or you can use the following map function in one Mapper Snap:

$cover.map(x => {
	"needCode":x.needCode,
	"needKindName":x.needKindName,
	"rates": x.hasPath("coverAmount") ? [{
			"type":"Cover Amount",
			"amount":{
			"value":x.coverAmount.amount,
			"currencyCode":x.coverAmount.currencyCode.toLowerCase()
			}
		}] : []
})

If you ask me, I would suggest going with the first approach if possible, since it is cleaner and easier to maintain.

Try both ways and let me know.
