Stored Procedure Call cofigured operationOracle problem

I have a stored procedure in oracle table. This proc has two inputs (eg say empid,position). When I am trying to create storedprocedure call configured operation in ES, I mentioned two input values in “Call” tab(empid,pos). If I see in “input” tab it is displaying that “no fields defined”. Can any body explain me how I need to configure this operation with two input parameters?

I found the answer for this, I used placeholders while configuring storedprocedure configured operation
