Table Cluster Creation - Help required.

Question

Hi,
I need to create a Table Cluster. My requirement is to create Table Cluster for MARA and 3 more 'Z' tables.
I read through the SAP documentation for the creation of table cluster. <http://help.sap.com/saphelp_nw04/helpdata/en/cf/21f083446011d189700000e8322d00/content.htm>
But when i tried creating 'Cluster Table' i am getting errors.
Please suggest the precautions to be taken while creating a Table Cluster, It would be of great help if any Mock document can be provided for creation of Table Cluster.
Quick help in this regard is much appreciated.
Many Thanks
Ramesh.

hi ramesh,
Creating Pooled Tables/Cluster Tables
Procedure
In the initial screen of the ABAP Dictionary select object type Table, enter a table name and choose  Create.
The field maintenance screen for the table is displayed. Table type Transparent table is set as default.
Make the necessary entries in the Short description and Delivery class fields on the Attributes tab page. Then define the fields of the table.
Proceed as when  creating a transparent table. Save your entries.
Choose Extras ® Change table category.
A dialog box appears in which you have to select the table type Pooled table or Cluster table.
Choose Select.
You return to the field maintenance screen for the table. Field Pool/cluster name is displayed on the Attributes tab page in addition to the standard fields.
Enter the name of the table pool or table cluster to which you want to assign the pooled table or cluster table in field Pool/cluster name
Note that the total key length of a pooled table may not exceed the key length of the associated table pool. The key of a cluster table must correspond to the key of the associated table cluster.
Proceed as when creating a transparent table (see  Creating Tables). Remember that you cannot create indexes for pooled or cluster tables.
All the attributes of the  technical settings can be maintained for pooled tables and cluster tables. Before you can access these attributes, however, you must convert the table to a transparent table.
Creating Table Pools/Table Clusters
Procedure
In the initial screen of the ABAP Dictionary, choose Utilities ® Further Dictionary Objects.
A dialog box appears.
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 .
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.
Enter an explanatory text in the field Short text.
If necessary, select the  activation type of the table pool/cluster with Utilities ® Activation type.
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.
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.
Activate the table pool/cluster with .
Result
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).
Once a table pool contains data, it can no longer be changed.
