Creating a Table Cluster

1. In the initial screen of the ABAP Dictionary, choose Utilities ® Pools/clusters ® Create pool/cluster.

A dialog box appears in which you must enter the name of the table cluster. Then choose Table cluster.

The maintenance screen for table clusters appears. Because table clusters have to have a certain structure, certain fields are already proposed during creation. You can adjust this proposal to your requirements, including further key fields, for example. However, make sure you conform to the structure necessary for a table cluster.

2. Enter an explanatory text in the field Short text.

3. If necessary, choose the activation type for the table cluster with Extras ® Activation type.

4. Choose Goto ® Documentation and enter documentation for the table cluster, describing the uses of the table cluster.

5. Branch to the maintenance screen for the technical settings by choosing Goto ® Technical settings. Unlike in the tables maintenance, here you can specify only the Size Category of the table cluster. All other attributes of the technical settings are preset.

6. Activate the table cluster with Table cluster ® Activate.

You can view the log for the activation procedure by choosing Utilities ® Act. log. If errors occurred when the table cluster was activated, you branch to the activation log directly.

After the table cluster has been activated, you need to create it in the database. To do this, use the database utility (Utilities ® Database utility).

Once a table cluster contains data, it can no longer be changed.
