How to use the results of WHINT InterfaceCatalog

The WHINT InterfaceCatalog for SAP PRO/PI generates two Excel Documents to bring more transparency to your interface landscape. Here is how you can better understand the results:

Channel Catalog

  • a list with all communication channels
  • contains all adapter attributes
  • contains all adapter modules
  • contains all parameters within each adapter module
  • You can filter and/or search for specific values as host names, user names, modules used, etc. across all channels



Interface Catalog

  • a list of all sender/receiver interface combinations
  • contains operation mappings used
  • contains routing (receiver determination and interface determination)
  • contains an assignment to configuration scenario(s)

Example iFlow / Integrated Configuration




is shown in the InterfaceCatalog as follows:


Usage Dependencies in Software Components

There is a useful functionality to reuse objects from one software component in another one.

You can define this usage dependency in SLD or in ESR (software dependencies & underlying software components).

It is needed if want to enhance Standard Enterprise Services or when you create a shared pool of objects that is strictly reused and not copied into other Software Components.

  • Data Type Enhancements (to enhance SAP Data Types)
  • Central Mappings, Function Libraries

Please do not use it to share interface objects across several components/systems.

Different release/deploy/maintenance cycles in the connected systems require a clearly decoupled approach which is also reflected by the software components. In case your data types/message types/service interfaces are equal in both software components, simply copy them over. Starting from then on, you have to add a new field in both components (or you copy again by overwriting the target object).

Key takeaway: Decoupling is more important than reuse (in this case)!

No Mapping required!

As your software components will use their own namespaces you should be careful designing the messages. When you copy over the message type from SWC_1 to SWC_2, the XML Namespace in SWC_2 will automatically have the Namespace of SWC_1. To use this feature smarter, simply use a cross-component, company-wide, global namespace.

XML Namespace in the Message Type: http://<company-domain>/xi/GLOBAL
Btw: This is approach is also used by SAP to design their namespaces.


  • SWC_1: OTC_RETAILER 2016 of
  • SWC_2: OTC_SAP_ERP 6.0 of
  • XML Namespace across all SWC:

Sync-Async Connectivity (SOAP 2 MAIL) with SAP PRO (w/out BPM)

Sync-Async Patterns with BPM on SAP NetWeaver Process Orchestration (PRO) are quite easy to implement.
However, when you want to design the integration flow as lean as possible, this document might be useful for you as the usage of the sync/async adapter modules is a bit tricky.


  • SOAP Sender (in our example WebShop) is calling SAP PRO synchronously
  • The request is forwarded asynchronously via E-Mail to the receiver (typically it would be e.g. IDoc to SAP ERP of course)

This is an example scenario of course. HTTP/SOAP on the (sync) sender side can be combined with any channel on receiver side (IDOC/SOAP/FILE/SFTP/MAIL/JMS/JDBC/…)

Adapter Modules used:

We are using the following (standard) adapter modules:

  • AF_Modules/RequestOnewayBean (to convert the synchronous message to an asynchronous one)
  • AF_Modules/DynamicConfigurationBean (to store the original message id in the ASMA of the sender channel and read it in the receiver channel to set the correlation)
  • AF_Modules/WaitResponseBean (to wait for the reply of the receiver channel)
  • AF_Modules/NotifyResponseBean (to send back the message to the waiting sender channel using correlation)

ESR Content (sender side):

  • Service Interface Sync Out
  • Service Interface Sync In (Dummy)
  • Operation Mapping (Service Interface Sync Out -> Sync In)
  • Message Mapping (Input Message Type -> Output Message Type)

DIR Configuration:

  • Sender System
    • SOAP Sender Channel
    • SOAP Receiver Channel
  • Receiver System
    • MAIL Receiver Channel


It is of course not necessary to do this in NWDS but I really started to like it…





Test & Monitoring:

  • Call WebService from WS Navigator
  • ASMA (DynamicConfiguration) with MessageId
  • E-Mail received from SAP PRO
