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.
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.

- 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.
  - 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.
      - 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.
        Overview of the R/3 adapters
        Adapter commands list
      - Intermediate Documents (IDocs)
      - 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.
- 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.

Overview of the R/3 adapters

Both client and server functionality is supported within an R/3 adapter. An R/3 adapter contains the Remote Function Calls (RFCs) necessary to pass inbound and outbound data to and from SAP R/3. The adapter includes transparent integration of the RFCs so that it is not necessary to possess detailed knowledge about the RFCs. The adapters also manage transactional information such as message transaction IDs (TIDs) as needed. This feature ensures seamless integration with SAP R/3 and also provides a robust auditing mechanism.

The R/3 adapters used to interface with the SAP R/3 application are:
