Table that stores Process Configuration Group values used in HCM extract run

Content

Could someone please help with the table name that stores the list of Process Configuration Group values that are used to run HCM extracts?

I'm looking to run HCM extract through web service https://emnk-dev1.fa.ap1.oraclecloud.com:443/hcmService/FlowActionsService?wsdl (submitFlow operation) for which it seems to need backend Id of Process Configuration Group. When we use front end name like DEFAULT GROUP, it errors saying - java.lang.NumberFormatException: For input string: "DEFAULT GROUP"

Web service input - 

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/&quot; xmlns:typ="http://xmlns.oracle.com/apps/hcm/processFlows/core/flowActionsService/types/&quot
