Procedure

...

       1.      On the initial screen of the ABAP Dictionary (transaction code SE11), choose Utilities ® Other Dictionary Objects.

A dialog box appears.

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

A new dialog box appears.

       4.      Select the required object type (Table pool or Table cluster) and choose  with the quick info text Continue.

The maintenance screen for table pools/clusters appears.

The system automatically makes the necessary entries for the fields for table pools since a table pool has a fixed structure.

You must not change these standard settings if you can avoid it.

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

Make sure you conform to the structure necessary for a table cluster.

       5.      In the Short Description field, enter an explanatory text.

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

       6.      To create documentation about the table pool/cluster, choose Goto ® Documentation.

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

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

You can define only the size category here. All other attributes of the technical settings are preset.

       8.      Choose  with the quick info text Save.

       9.      Choose  with the quick info text Activate.

Result

The table pool/cluster is activated.

To look at the activation log, choose Utilities  ® Activation Log. If errors occur during activation, the system automatically displays the activation log.

After the table pool/cluster has been activated, you need to create it in the database. To do this, use the database utility. To go to the database utility initial screen, choose Utilities ® Database Utility.

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