Hi Divya,
Please refer the JDBC Adapter guide for details regarding SPwithSignature.
Also check if we have right privileges on DB for that SP to invoke. I believe Function/SP should show up if we have right privileges.
Else you can try to expose that Function as SP in oracle and give a try if that helps.
Other alternative is Custom SQL adapter template you can use the same if the above didn’t work.
