Yes, however, I will close this thread accepting as solution. I have bigger integration step where I need to write values to mockResponse file, then again filter the xml response back from same file. Just let me know if below scenario can be achived ? You have already provided solution for STEP1 earlier. If doable, I can open a new thread, whatever you suggest.
GetBill_Request ---> Input = (MODE=SUBMITTEDORCORRECTED and ContractSolutionNumber=globalproprty)
GetBill_Response ---> Get globalproperty.xml as response
setBill_Request Input= ContractSolutionNumber and Account numbers (write account numbers to same file globalproperty.xml)
GetBill_Request (Mode=LITE) ContractSolutionNumber
GetBill_Response (From same file globalproperty.xml, get the Filtered XML response)
