Creating Table Pools/Table Clusters 

Procedure

1. In the initial screen of the ABAP Dictionary, choose Utilities ® Further Dictionary Objects.

A dialog box appears.

2. Select the object type Table pool/cluster and enter the object name. Choose .

A dialog box appears in which you must specify if it is a table pool or a table cluster.

Select the required object type and choose .

3. The maintenance screen for table pools/clusters appears.

The necessary entries will have been made automatically for the fields for table pools since a table pool has a fixed structure. You should not change these standard settings if you can avoid it.

The structure of a table cluster is also mostly fixed. Certain fields are therefore proposed when the table cluster is created. You can adjust this proposal to your requirements, for example by inserting further key fields. However, make sure you conform to the structure necessary for a table cluster.

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

If necessary, select the activation type of the table pool/cluster with Utilities ® Activation type.

5. Create documentation about the table pool/cluster with Goto ® Documentation.

This documentation should describe what the table pool/cluster is used for. The documentation is also output when the table pool/cluster is printed.

6. Go to the maintenance screen for the technical settings by choosing Goto ® Technical settings.

In contrast to the table maintenance screen, you can only define the size category here. All other attributes of the technical settings are preset.

7. Activate the table pool/cluster with .

The table pool/cluster is activated. You can look at the log of the activation with Utilities ® Activation log. If errors occurred during activation, the activation log is automatically displayed.

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