The previous blog of this series - SAP Co-Innovation Lab Architecture Series: Partner-delivered Enterprise Service - Modeling Services ...- showed the path of creating the model entities (process component model, business object, etc.) for the Read Sales Order scenario. The next step is to derive the actual service definition from the model ultimately receiving a design time WSDL.
The Enterprise Services Builder (ES Builder) tool as part of the Enterprise Services Repository (ESR) remains the working environment for the steps of
- Creating service interface and operation definitions
- Assigning the previously created model entities to the respective definitions
- Creating Message Types and Fault Message Types
- Creating Message Data Types
- Detailing the message structure down to the element level
- Data typing
The attached screencam is targeted to guide you through exactly these steps building upon the ESR content that has been created in the screencam in the previous blog on service modeling.
We recommend reading Dirk Richtsteiger's and Michael Seubert's SAP Global Data Types Catalog. It gives a great introduction to the concept of Global Data Types (GDTs). Here you will find as well the link to the GDT catalog in PDF format. This PDF document not only provides the actual catalog of Core Data Types (CDT) and GDTs with detailed documentation. In the introduction the overall topic of data typing is very well described. So continue on your PdES journey and have a look at the screencam (please note the corrections below):
Correction note: The intermediate data types (IDT) in the screencam have been erroneously derived from the message data type (MDT), e.g. SlsOrdByIDQryMsg_syncSlsOrdSelByID. This is not correct: The IDT names must be derived from the message type (MT) name. In the example above the IDT name should be SlsOrdByIDQry_syncSlsOrdSelByID. The naming in the storyboard below are correct.
The detailed storyboard is outlined in the following:
- Create a Repository Namespace
Name: http://mycompany.com/
- Create a Service Interface
Name: SalesOrderProcessingManageSalesOrderIn
Namespace: http://mycompany.com/
Category: Inbound
Interface Pattern: Stateless
Description: "Groups operations that read, create, change, delete, or update an House shipment, or parts of it."
- Delete automatically created default operation
Name: SalesOrderProcessingManageSalesOrderIn
- Create an Operation
Name "ReadSalesOrder"
Mode: Synchronous
Description: "Reads a unique sales order instance"
- Create model assignments of service interface and operation to corresponding definition entities
- Define Operation Structure and create Message Types
Request Message Type: SalesOrderByIDQuery_sync
Response Message Type: SalesOrderByIDResponse_sync
Fault Message Type: StandardMessageFault
- Create Message Data Types
Request Message Data Type: SalesOrderByIDQueryMessage_sync
Response Message Data Type: SalesOrderByIDResponseMessage_sync
Fault Message Type - Standard Data: ExchangeFaultData
- Define Message Data Type Structure
Request Message Data Type structure:
Content node: SalesOrderSelectionByID
Typed by: Intermediate Data Type (IDT) SlsOrdByIDQry_syncSlsOrdSelByID
[Type name derived using abbreviation concept based on GDT AbbreviationCode]
Only element: ElementID
Typed by: GDT NOSC_SalesOrderID
