@Jyoti_Sinha Sorry for the late reply. Price update worked 
Thank you for that.
My question on RatePlanChargeTier still exists and it is confusing me a lot.
I have created a Product with only one RatePlan.
I have executed the following queries to get the price.
Procedure-1: POST https://rest.apisandbox.zuora.com/v1/action/query
==========
ProductId - {"queryString":"SELECT id from Product where name='xxxxxx'"}
ProductRatePlanId - {"queryString":"SELECT id from ProductRatePlan where ProductId='xxxxxx'"}
ProductRatePlanChargeId - {"queryString":"SELECT id from ProductRatePlanCharge where ProductRatePlanId='xxxxxx'"}
ProductRatePlanChargeTierId - {"queryString":"SELECT id from ProductRatePlanChargeTier where ProductRatePlanChargeId='xxxxxx'"}
-- Here I have got only one Id in the response
Update the price:
{
"type": "ProductRatePlanChargeTier",
"objects": [{
"Price": 351.00,
"Id":"2c92c0f95ad9c24d015addf33b090b12"
}]
}
Procedure-2:
==========
Tried to get the ProductRatePlanChargeId using Datasource by using Product name as a query filter. I am attaching the export result file here. Wonder why I have 5 rows.
