The use of the Incomes Register can be restricted with defining specifiers

Two defining specifiers are used in the Incomes Register to limit authorisations: the suborganisation identifier and customer ID.

The defining specifiers apply to the Incomes Register's authorisation codes Reporting earnings payment data and Browsing earnings payment data as well as Reporting benefits payment data and Browsing benefits payment data.

Suborganisation identifier

The payer uses the suborganisation identifier to divide its company into separate entities for the purposes of using the Incomes Register. The company can use the suborganisation identifier to, for example, differentiate between the organisation's business departments, such as payroll and travel expense claim management.

authorisation code and suborganisation identifier
