Constraints
With this version of the Integration Directory programming interface you can only access configuration object types or object attributes that are already available in SAP NetWeaver Process Integration 7.0 or SAP Exchange Infrastructure 3.0. Configuration object types and attributes that are available as of SAP NetWeaver PI 7.1. are not supported by this version of the interface.
Note
This concerns object types Direct Connection, Process Components and Integrated Configuration and the access to service interface operations in an interface determination.
If you want to activate or check a change list that contains objects that were not supported in previous releases, the operation is cancelled and an error message is displayed.
This restriction concerns read and write operations on objects, as well as reading the contents of a change list.
Caution
Ensure that for the Search for Object (Query) operation that the key of the object is also determined for objects that were not supported in previous releases. This can cause problems for clients that are not set for this situation.
