Issue/Introduction

Description:

SAP can be installed on single or on multiple Java instances. A SiteMinder ERP agent can be installed on it and a Webagent at the Front End. When we use a multiple Java instances, ERP Agent fails to handle headers properly and and log "TransactionID header not found or empty - Aborting" Architecture:

SAP in cluster with 2 Java instances. The sap portail uses the session affinity.
When we switch from 1 instance to the other it seems that HTTP headers are lost.

Solution:

CA has certified and tested the ERP agent with SAP Server having single AS Java server instance. Hence CA doesn't support this combination.
