BSO Web ServiceServiceImplementation we have to Validate the Session Login using below method Ctx.g

We have requirement to Update the shipment Line. for this we are using BSO as suggested in  Doc ID 1573389.1. We are able to trigger BSO Web Service and Perform the required operation, But in the ServiceImplementation we have to Validate the Session Login using below method

 

Ctx.getSessionManager().validateLogin("USERNAME","PASSWORD");

 

here we do not want to hardcode the values but use it from Concurrent Program context so that it takes the session values of concurrent.

 

Can you please suggest, How can we do it.?
