Reference Guide
This guide describes conceptual information about data design environment components when you want to use the data fabrication feature in HCL OneTest™ Server.
Connections
A connection defines the properties that are required to connect to an external resource. An action uses a connection to provide source data to a project or write data from a source to a target. Multiple actions can use the same connection. You can define both connections and actions at the project level.
Resource adapters
HCL® OneTest™ Data resource adapters are used to retrieve data. These resource adapters provide access to the databases.
SAP applications
This topic provides an information about integration of SAP applications with HCL® OneTest™ Data.
Introduction
The Systems Applications and Products in Data Processing (SAP) applications acts as resource adapters. HCL® OneTest™ Data integrates with the SAP application to generate a schema, and then generate the test data to perform application testing.
SAP applications overview
Overview of SAP R/3 interfaces
Intermediate Documents (IDocs)
The IDocs interface consists of the definition of a data structure and the processing logic for this data structure. This interface is used to exchange business data between two different systems. SAP R/3 support for the IDoc interface includes both Electronic Data Interchange (EDI) and Application Link Enabling (ALE) technologies.
ALE Message Handler (AMS)
The AMS interface provides connectivity between SAP R/3 and one or more disparate applications sending and receiving IDocs for one or more SAP R/3 instances. AMS does not provide any conversion function and delivers IDocs without changing them. Transactional RFC must be the communication method used between the SAP R/3 system and the ALE Message Handler.

- Files
  You add a file to a project to use it as input in the project. You can upload a file from your local file system to a project from the Files tab to generate test data. Alternatively, you can upload it when you define an action.
- Connections
  A connection defines the properties that are required to connect to an external resource. An action uses a connection to provide source data to a project or write data from a source to a target. Multiple actions can use the same connection. You can define both connections and actions at the project level.
  - Project-level connections
    You can reuse project-level artifacts in multiple projects. You use the Connections tab to define a new project-level connection and its actions or to select an existing project-level connection and its actions.
  - Connection testing
    You can test project-level connections. When the Design Server has access to an external resource, testing validates the properties of the resource connection. If the Design Server can not access the external resource, the connection test fails, even if the connection properties are correct.

        Intermediate Documents (IDocs)
        The IDocs interface consists of the definition of a data structure and the processing logic for this data structure. This interface is used to exchange business data between two different systems. SAP R/3 support for the IDoc interface includes both Electronic Data Interchange (EDI) and Application Link Enabling (ALE) technologies.
        Application Link Enabling (ALE)
        ALE links multiple SAP R/3 systems in distributed environments, and non-SAP systems to SAP R/3 without file-to-file transfers. The SAP R/3 architecture supports the transfer of data between applications using messaging as opposed to files. SAP R/3 enables the creation of a distributed, fully integrated suite of loosely coupled applications.
        ALE Message Handler (AMS)
        The AMS interface provides connectivity between SAP R/3 and one or more disparate applications sending and receiving IDocs for one or more SAP R/3 instances. AMS does not provide any conversion function and delivers IDocs without changing them. Transactional RFC must be the communication method used between the SAP R/3 system and the ALE Message Handler.
        Electronic Data Interchange (EDI)
        EDI enables companies with the ability of communicating business transactions and documents electronically with their partners, vendors, and clients.
        DXOB/Data Migration Interface (DMI)
        DXOBs are SAP R/3 business objects that can be transferred automatically into the SAP R/3 system. Examples of business objects are organizational units.
        Business Application Programming Interface (BAPI)
        The BAPI adapter (JBAPI) enables full Unicode support when installed with the latest version of ITX. The JBAPI adapter provides unified access to both Unicode and non-Unicode systems.
      - The R/3 adapters
        The SAP specific components for the SAP R/3 runtime environment are the R/3 adapters for Windows™ based and UNIX™ based platforms.

        The BAPI adapter (JBAPI) enables full Unicode support when installed with the latest version of ITX. The JBAPI adapter provides unified access to both Unicode and non-Unicode systems.
- Schema design
  A schema is a graphical data dictionary that contains metadata definitions of the structure of a document to generate test data. Schema provides visual cues for understanding the structure and complete definition of an object.

ALE Message Handler (AMS)

The AMS interface provides connectivity between SAP R/3 and one or more disparate applications sending and receiving IDocs for one or more SAP R/3 instances. AMS does not provide any conversion function and delivers IDocs without changing them. Transactional RFC must be the communication method used between the SAP R/3 system and the ALE Message Handler.
