Validation and derivation rules
APRA uses validation rules in D2A to validate the data submitted by reporting entities. Entities are expected to correct any reporting errors identified by these rules.
There are two types of D2A validation rules: mandatory and confirmation rules. Mandatory rules identify data, within D2A, that contain mathematical errors and discrepancies or factual inconsistencies. Entities must correct all data that fail mandatory rules to submit data via D2A. Confirmation rules identify data, within D2A, that indicate reporting errors or require explanation. Entities are expected to correct or explain data identified by confirmation rules within D2A.
Derivation rules are formulae that automatically calculate ('derive') values for attributes, in most cases using the values for other attributes as inputs.
The rules are updated two weeks prior to the end of each quarter ending 31 March, 30 June, 30 September and 31 December.
