    Hi,

    In v10, we added a wizard for containment creation to make it simpler ... these steps apply to previous versions:

    A containment is where a BObj contains a nested child BObj in XML requests and responses, for example: TCRMPersonBObj has the child object TCRMPersonNameBObj. As well as the nesting in the XML, there is also a relationship between the database tables and the add/update/get transactions for the parent object handle adds,updates and queries for the child objects.

    1. Right-click the parent entity, New - Containment
    2. Give the Containment a name
    3. Select the contained entity - can be an out-of-the-box entity, data addition, or transient data object
    4. Set the 'Many' flag if you want multiple child objects for a given parent.
    5. Set 'Derived from' reference - this is the reference (foreign key) field which is used to connect together the database tables. You don't have to set this - if you don't then the generated code won't manage the parent/child relationships for you, but you can customize the code to do this yourself.
    6. Set the 'Inquiry' transaction - this is an inquiry transaction which is used to get the child object(s) for a given parent. You don't have to set this - if you don't then the generated code won't manage the parent/child relationships for you, but you can customize the code to do this yourself.
    If the contained entity is an out-of-the-box entity, and Many is true - you won't have a Derived from and Inquiry transaction, and you'll have to write the code to manage the parent/child add, update and get logic.

    If the contained entity is a data addition, then you can define on it a suitable reference and inquiry transaction if needed. If Many is true, define a Reference on the child entity which refers to the parent entity - that's the Derived From. Define a GetRecord transaction which queries the child entity by the parent reference field, that's the Inquiry transaction.

    If Many is false, then you can either have a reference field on the child entity (referring to the parent) or on the parent entity (referring to the child). If the latter, you don't need to define a special Inquiry transaction, because the standard get by primary key can be used.

    If the contained entity is a transient data object, then the Derived from and Inquiry settings won't be used - you again need to customize the code to do whatever logic you want to handle the child objects.

    Hope that helps, Catherine.
