MDG_TR_REORG - Table Entries for Transport Container

This documentation is copyright by SAP AG.

The tables for the transported data constantly increase in size through frequent Customizing transports with the transport tool of the Master Data Governance Application Framework. This may result in poor performance. With this activity, you reorganize these tables to delete table entries that are no longer required.

During the reorganization, the system deletes the table entries referenced by the transport requests in the transport tables (for example, MDG_MDFTRANS). Since this involves redundant data only, you can perform the reorganization without taking any risks. However, the detailed composition of the object list of a transport request can no longer be recognized after the reorganization.

The reorganization can be useful both in the source system and in the target system of the transports. You can delete table entries on successful exports (source system) or successful imports (target system) depending on in which system you perform the activity.

Note: This activity is optional. You only need to perform the reorganization when you think that the size of the transport tables makes this necessary.

You can either start collective or single processing of transport requests:

• Collective Processing

All obsolete table entries are deleted, in particular entries on already deleted transport requests and on executed client copies. Collective processing with the standard option 'Delete Obsolete Entries' is suitable for periodic scheduling as a background job.

Optionally, you can delete entries on transport requests that still exist (successful imports or exports). All entries on the selected transport requests are deleted in this option. You can also delete these requests if the request status permits this.

• Single Processing

You can specifically delete entries on individual transport requests. Optionally, the request can also be deleted (for example, test requests).

If entries are deleted during an update run, this is logged in the application log under the object MDG_TR (MDG: Transport Tool), subobject REORG (Reorganization).

In a test run, the system displays the number of data records to be deleted for each table.
