  1. The SAP Java Connector (SAP JCo) is a development library that enables a Java application to communicate with on-premise SAP systems via SAP’s RFC protocol. It combines an easy-to-use API with unprecedented flexibility and performance. The SAP JCo supports both communication directions: inbound Remote Function Calls (Java calls ABAP) as well as outbound Remote Function Calls (ABAP calls Java).

  2. Do you know what are the new functionality or features with SAP Jco 3.1 as compared with 3.0.x version?

    1. Hi John,

      Please be carefull. SAP PI 7.31 is based on SAP EHP1 for SAP NW 7.3. This version is already out of support per 31.12.2020.
      This outdated version will most likely only work with outdated JCO.

      Please check the SAP PAM site for software updates on PI itself. If you update PI, the JCO version update will normally be included.
