Defining Explicit Key Mapping

Prerequisites

  • You have created a data object and have added the required nodes.

  • The individual nodes contain back-end fields that hold the back-end keys of the nodes higher up in the node hierarchy of this data object.

  • You have saved the nodes.

Context

To ensure referential integrity between the nodes of a data object, the back-end keys of the nodes higher up in the node hierarchy of the data object must also be available as back-end fields in the child nodes. The corresponding fields must be mapped to each other. One option for mapping these keys is the explicit key mapping function in the data object Builder.

Procedure


  1. Log on to the SAP NetWeaver AS and start transaction SDOE_WB .

  2. In the Data Orchestration Workbench , click the required child node with the secondary mouse button and choose Change .

  3. Choose Explicit Key Mapping .

    The parent node name(s) and parent node attribute(s) acting as the back-end key(s) are displayed in the Explicit Key Mapping tab page.

  4. Choose Display/Change .

  5. In the Node Attribute column, select the child node attribute that you want to map to the parent node attribute.

  6. Choose Save .
