Function documentationKey Mapping Locate this document in the navigation structure

 

You can use this function to create mappings between object instances by connecting their object IDs.

In business processes with several systems, each object instance requires one or more object IDs to ensure it can be identified and mapped to other object instances. During data replication, the object instance is replicated from a central system to one or more target systems. In the process, each system can use its own logic to create object IDs.

Features

Creation, Editing, and Deletion of Key Mapping information

To create, change, or delete key mapping information, you can complete the following actions:

Direct Access to Key Mapping Information

To access key mapping information directly, you can complete the following actions:

  • Use the Search Key Mapping Web Dynpro application.

    For more information, see Searching of Key Mapping Information.

  • Call the key mapping Application Programming Interface (API) within your programs.

Remote Access to Key Mapping Information

You can access key mapping information from the central registry of a client system. This is only possible if, in Customizing, you have defined a business system as a central registry for each business object that uses key mapping.

When you access key mapping remotely, you have the following options:

  • Extending key mapping for an existing object

    With this option, you must define an object ID type and you may have to define an object node type for the object ID type.

  • Using key mapping for your own business objects

    With this option, you must define an object ID type and an object node type for the object ID type.

Note Note

You can apply the relevant settings in Customizing for Master Data under   General Settings   Key Mapping   Customize Business Objects for Key Mapping  .
