Getting the list of approvers/approver groups of a PR

Hello Team,

I'm required to get the list of approvers/approver groups in a PR generated in iProcurement module. I have achieved this using the below function.

ame_api2.getAllApprovers7
(applicationIdIn => fndApplicationId
,transactionTypeIn => transactionTypeId
,transactionIdIn => transactionId
,approvalProcessCompleteYNOut => finish
,approversOut => approvers);

Is there any other way to achieve the same? By querying a table or a view? Please advise.
