We are trying to implement the QR code through ABAP program. We are following the steps mentioned in the link "https://blogs.sap.com/2013/10/15/how-to-create-a-qr-code-and-show-it-in-a-smartform/".
When we try to execute the code, it says "HTTP Communication Failure" in the statement "http_client->receive( )". Is there any alternate statement/solution for this?
Our SAP version is 701 and kernel version is 721. We raised a snote to SAP and they replyed to upgrade the system. We cannot upgrade our sap system as the client is not willing to do so. How do we solve this error? Is there any configuration settings we need to maintain, if so what and where should we maintain them?
