There are two new callable object types:
● User Mapping (Conversion between AS Java and AS ABAP Identities)
Use this object to perform bidirectional conversions of AS Java (UME) unique user IDs to their corresponding AS ABAP unique user IDs. As a prerequisite, you must have configured access to an AS ABAP system by creating a system landscape object with a system alias in the portal.

You are advised to replace the Resolve Manager of User (Requires SAP HR) callable object available in previous releases with a combination of the following:
...
■ User Mapping (Conversion between AS Java and AS ABAP Identities) callable object for conversion of user IDs
■ An External Service callable object which performs a CAF_EU_GP_MANAGER BAPI call to find employee managers from an AS ABAP HR system, specified with a system name.

● Pass Through Form
Use this object to transfer instances of composite forms (PDF files) between process steps. The callable object also allows you to download and modify the input form online.
