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.

- 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.

        IDoc structural format
        Data Transfer Objects (DXOB)
      - 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 IDocs

Several hundred IDocs are shipped with each SAP R/3 system. ALE and EDI interfaces use functionally equivalent IDocs; however, they differ in the manner in which the IDocs are communicated to or from SAP R/3.

ALE IDocs are communicated through memory buffers, without intermediate files, directly to or from an RFC port using transactional remote function calls (RFCs).
EDI IDocs are passed using an intermediate file.

These interfaces (ALE and EDI) that use the IDoc structure represent SAP's strategic approach to interfacing SAP R/3 with legacy and third-party applications where loose coupling is appropriate. Therefore, the SAP R/3 IDoc approach should be considered the first choice for developing interfaces where asynchronous, near-real time, or batch links are required. This pack supports SAP-supplied IDocs as well as user-defined IDocs.

One or more IDocs are held in a container called a packet. A packet is the largest data container in an IDoc schema. The restart attribute is automatically added to reject invalid IDocs contained within a packet.
