Hi Anil,
Thank you for the clarifications.
Upon checking the provided screenshots, it appears that you want to get the cost at the account level. With this, you may use instead the
customer report and include the
metrics.cost_micros field. For your convenience, you may use the query below as the date range you mentioned are considered:
SELECT metrics.cost_micros, customer.descriptive_name, customer.id FROM customer WHERE segments.date DURING LAST_MONTH
Also, since you want to get the cost of the multiple accounts the
Parallel Report Download can still be used in your use case.
