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.

This topic provides an information about integration of SAP applications with HCL® OneTest™ Data.

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.
- 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.

IDoc structural format

The IDoc format consists of hierarchically structured segments with multiple levels of nesting. IDocs exist for data such as customers and materials, for transactional data such as sales orders, and for control data such as company codes. In ALE terms, these are called IDoc types, which are described as follows:

Control record: There is one control record, and its format is identical for all IDoc types. It consists of the IDoc ID, Sender ID, Receiver ID, IDoc type, and EDI attribute.
Data records: There can be one or more data records. A data record consists of a fixed administration section (IDoc ID, Sequence/Hierarchy) and a data part (Segment). A Segment is the formal definition for header data and item data. The number and format of the segments can be different for each IDoc type.
Status records: The status records describe the processing stages through which an IDoc can pass, and contain the IDoc ID and status information. There will be several status records.

The IDoc types are assigned to release-independent message types, which themselves are assigned to object types in the Business Object Repository (BOR). Customer enhancements are generally subject to naming conventions. IDoc data segments are a maximum of 1000 bytes in length and generally only contain CHAR fields. The data segments of an IDoc type are described by release-independent segment types and have release-specific segment definitions that are stored as internal structures in the Dictionary. This means IDocs can be sent with different data contents to different recipients because the recipient's release is defined in the sending system.
