How to Register a custom table in Oracle 11i/R12.

You can register your custom application tables using a PL/SQL routine in the AD_DD package.
Flexfields and Oracle Alert are the only features or products that depend on this information. Therefore you only need to register those tables (and all of their columns) that will be used with flexfields or Oracle Alert.
You can also use the AD_DD API to delete the registrations of tables and columns. You should delete the column registration first, then the table registration.

To alter a registration you should first delete the registration, then re-register the table or column.
The AD_DD API does NOT check for the existence of the registered table or column in the database schema, but only updates the required AOL tables. You must ensure that the tables and columns registered actually exist and have the same format as that defined using the AD_DD API.

You need NOT register views.

You should include calls to the table registration routines in a PL/SQL script.

You should run the AD_DD procedures against the APPS schema. You must commit your changes for them to take effect.

Procedures in the AD_DD Package:
procedure register_table (p_appl_short_name in varchar2,
p_tab_name in varchar2,
p_tab_type in varchar2,
p_next_extent in number default 512,
p_pct_free in number default 10,
p_pct_used in number default 70);

p_appl_short_ name: The application short name of the application that owns the table (usually your custom application).
p_tab_name: The name of the table (in uppercase letters).
p_tab_type: Use 'T' if it is a transaction table (almost all application tables), or 'S' for a "seed data" table.
p_next_extent: The next extent size, in kilobytes. Do not include the 'K'.
p_pct_free: The percentage of space in each of the table's blocks reserved for future updates to the table (1-99).
p_pct_used: Minimum percentage of used space in each data block of the table (1-99). The sum of p_pct_free and p_pct_used must be less than 100.

procedure register_column (p_appl_short_name in varchar2,
p_tab_name in varchar2,
p_col_name in varchar2,
p_col_seq in number,
p_col_type in varchar2,
p_col_width in number,
p_nullable in varchar2,
p_translate in varchar2,
p_precision in number default null,
p_scale in number default null);

p_col_name: The name of the column (in uppercase letters).
p_col_seq: The sequence number of the column in the table (the order in which the column appears in the table definition).
p_col_type: The column type ('NUMBER', 'VARCHAR2', 'DATE', etc.).
p_col_width: The column size (a number). Use 9 for DATE columns, 38 for NUMBER columns (unless it has a specific width).
p_nullable: Use 'N' if the column is mandatory or 'Y' if the column allows null values.
p_translate: Use 'Y' if the column values will be translated for an Oracle E-Business Suite product release (used only by Oracle E-Business Suite products) or 'N' if the values are not translated (most application columns).
p_precision: The total number of digits in a number.
p_scale: The number of digits to the right of the decimal point in a number.

procedure delete_table (p_appl_short_name in varchar2,
p_tab_name in varchar2);

procedure delete_column (p_appl_short_name in varchar2,
p_tab_name in varchar2,
p_col_name in varchar2);

Example:

EXECUTE ad_dd.register_table('FND', 'CUST_FLEX_TEST', 'T', 8, 10, 90);
EXECUTE ad_dd.register_column('FND', 'CUST_FLEX_TEST', 'APPLICATION_ID', 1, 'NUMBER', 38, 'N', 'N');
EXECUTE ad_dd.register_column('FND', 'CUST_FLEX_TEST', 'ID_FLEX_CODE', 2, 'VARCHAR2', 30, 'N', 'N');
EXECUTE ad_dd.register_column('FND', 'CUST_FLEX_TEST', 'LAST_UPDATE_DATE', 3, 'DATE', 9, 'N', 'N');
EXECUTE ad_dd.register_column('FND', 'CUST_FLEX_TEST', 'LAST_UPDATED_BY', 4, 'NUMBER', 38, 'N', 'N');
EXECUTE ad_dd.register_column('FND', 'CUST_FLEX_TEST', 'UNIQUE_ID_COLUMN', 5, 'NUMBER', 38, 'N', 'N');
EXECUTE ad_dd.register_column('FND', 'CUST_FLEX_TEST', 'UNIQUE_ID_COLUMN2', 6, 'NUMBER', 38, 'N', 'N');
EXECUTE ad_dd.register_column('FND', 'CUST_FLEX_TEST', 'SET_DEFINING_COLUMN', 7, 'NUMBER', 38, 'N', 'N');
EXECUTE ad_dd.register_column('FND', 'CUST_FLEX_TEST', 'SUMMARY_FLAG', 8, 'VARCHAR2', 1, 'N', 'N');
EXECUTE ad_dd.register_column('FND', 'CUST_FLEX_TEST', 'ENABLED_FLAG', 9, 'VARCHAR2', 1, 'N', 'N');
EXECUTE ad_dd.register_column('FND', 'CUST_FLEX_TEST', 'START_DATE_ACTIVE', 10, 'DATE', 9, 'N', 'N');
EXECUTE ad_dd.register_column('FND', 'CUST_FLEX_TEST', 'END_DATE_ACTIVE', 11, 'DATE', 9, 'N', 'N');
EXECUTE ad_dd.register_column('FND', 'CUST_FLEX_TEST', 'SEGMENT1', 12, 'VARCHAR2', 60, 'Y', 'N');
EXECUTE ad_dd.register_column('FND', 'CUST_FLEX_TEST', 'SEGMENT2', 13, 'VARCHAR2', 60, 'Y', 'N');
EXECUTE ad_dd.register_column('FND', 'CUST_FLEX_TEST', 'SEGMENT3', 14, 'VARCHAR2', 60, 'Y', 'N');
EXECUTE ad_dd.register_column('FND', 'CUST_FLEX_TEST', 'SEGMENT4', 15, 'VARCHAR2', 60, 'Y', 'N');
EXECUTE ad_dd.register_column('FND', 'CUST_FLEX_TEST', 'SEGMENT5', 16, 'VARCHAR2', 60, 'Y', 'N');
