A One-To-Many Extension Table Stores Data From Multiple Business Components

A one-to-many extension table is a table that you can use to track an entity that includes a one-to-many relationship with a parent business component but that a predefined business component does not represent. Note the following:

• You can store data for multiple business components in a one-to-many extension table.

• You use the Type column to group records in a one-to-many extension table.

• You configure each business component to get only the rows of a single type.

• A one-to-many extension table can contain multiple rows for a single row in the base table.

• The name of a one-to-many extension table includes an _XM suffix.

• Similar to a one-to-one extension table, a one-to-many extension table includes a set of generic ATTRIB_nn columns that you can use to store custom data.

• Unlike a one-to-one extension table, the value in the Type property of a one-to-many extension table is Data (Public) rather than Extension.
