Background documentation Home Data Source  Locate the document in its SAP Library structure

A home data source is the primary data source for a principal. It generates the unique ID for principals that it is home for. The home data source replies to existence checks: If a principal does not exist on its home data source, then it does not exist at all. Each principal can only have one home data source.

The strong relationship between a principal and its home data source is reflected in the unique ID of a principal. The unique ID is built in the following way:

<Principal_Type>.<Home_Data_Source_ID>.<Uniquename>

where:

·        <Principal_Type> = The principal type. This should be four upper case letters (A-Z).

¡        Names with the first letter in the range [A-W] are reserved for SAP.

¡        Names with the first letter in the range [X-Z] are reserved for customers.

¡        Exceptions are the predefined standard types: user, group, account, role, team.

·        <Home_Data_Source_ID> =The ID of the home data source

For more information, see <dataSources>.

·        <Uniquename> = Unique identifier for the principal on the home data source

Example

USER.CORP_LDAP.madams

Every user that is read from the LDAP server starts with USER.CORP_LDAP. if the ID of the LDAP data source from which the user was received is CORP_LDAP. During search or read operations, the home data source of a principal is immediately visible from the principal’s ID. For create operations, the configuration must specify the principal’s home data source.
