PO Response Time

Hello All,

I am doing PO - SalesForce integration. I am working on a Synchronous call (Outbound) , just need to know what would be the PO Waiting Time, until it gets the Response from SalesForce?

and Do we get Session Timed Out error, if the Response msg is not reaching PO withinh a Time frame?

Can we set this (Response Time) parameter anywhere in SAP PO?

Regards

Karthi
