Creation, Editing, and Deletion of Key Mapping Information

You use this Web Dynpro application (MDG_BS_WD_ID_MATCH_SERVICE ) to create, edit, or delete key mapping information for object instances, by creating, editing, or deleting records in mapping groups.

A mapping group specifies the key mapping data for object IDs that are mapped to each other. Each mapping group includes an object type, a business system, an object ID type, and an object ID. Each object instance can have one or more object IDs.

Prerequisites

You have authorization to create and edit data from the authorization object MDG_IDM.
You have defined mapping groups.
To facilitate data entry, we recommend that you sort long lists by object type.

Features

You can search for and then modify a key mapping group.

To search for the key mapping group, you specify details for one record. The search returns the record (if it exists) and all object instances whose object IDs map to the object ID you specified.

Note Note

A search that returns 0 records is valid. You can create a new mapping group based on the search criteria

End of the note.

Activities

Search for a mapping group by specifying the following details about one record in the mapping group: object type, business system, object ID type, and object ID.
A list containing 0-n rows of object instances whose object IDs map to the object ID you searched for is displayed. If the list contains 0 rows, an information message states that key mapping data does not exist for the selected ID.

Add, edit, or delete rows. For details, refer to the table below.

Action	Description
Add	Choose the Add Row button and add the relevant information. When entering data for new rows, note the following: If several rows refer to the same object, we recommend you give them the same number This ensures key mapping data is consistent. You can overwrite the auto-generated numbers. If you add a row that refers to an object ID that is already mapped to other object IDs, the system adds extra rows for all of the mapped object IDs. This only happens after you choose the Save pushbutton. For example, suppose object ID B is already mapped to object ID C. If you map object ID A to object ID B, object IDs A, B, and C all become part of the same mapping group.
Edit	To edit key mapping data, overwrite the cell data where this is allowed.
Delete	To delete key mapping data, select a row and choose the Delete Row pushbutton. If you delete all rows for an object, the complete object is deleted from the key mapping database.
