Using Previous Adapter Type Versions

For compatibility reasons, versions of the adapter type WS are offered which were available with previous releases of SAP Process Integration (SAP NetWeaver PI 7.1 or SAP enhancement package 1 for SAP NetWeaver PI 7.1). Use the older versions ( SAP BASIS 7.10or SAP BASIS 7.11) in cases where you have performed configuration work on the basis of such an earlier SAP PI release and you now want to proceed with this work on the basis of the current release.

For specific cases, SAP recommends using one of the previous versions.

It is generally recommended that you always select the adapter type version that corresponds to the oldest release of all the backend systems that are connected. When configuring direct communication between the Web service provider and Web service consumer you must determine the lowest backend release between the provider and consumer. When configuring Integratin Server communication you must determine the lowest backend release between the Integration Server, provider, and the consumer.

If addition you must use the older adapter type version if you want to configure direct communication between an ABAP-based and a Java-based backend system (irrespective of the release of the Java backend system).

By default you can only select the current adapter type version in the communication channel editor. To be able to select the older adapter type version, you must first import the relevant adapter metadata into the ES Repository.
