Determining Availability of a Predefined Extension Column

You must determine whether a predefined Siebel application uses or does not use the table column before you use a predefined extension table. To do this, you search the Siebel repository for fields that Siebel CRM associates with the column.

Caution: If a predefined field references a column, then do not deactivate the field.

To determine availability of a predefined extension column

1. In Siebel Tools, in the Object Explorer, click the Flat tab.

2. In the Object Explorer, click Field.

3. In the Fields list, create a query using values from the following table.

   Property	Value
   Column	Name of the column you must use.
   Join	Name of the extension table you must use.

4. If the query does not return any Field object definitions, then Siebel CRM does not use the column in the extension table and it is available.

5. If the query returns one or more object definitions, then you must find another extension column in this table. To identify the extension columns that Siebel CRM currently uses, do the query again using values from the following table.

   Property	Value
   Column	ATTRIB*
   Join	Name of the extension table you must use.
