Driver types

These driver types are supported:

Non-forecasted, non-propagated
- WDDDRIVER dimension attribute PropagateValues value: FALSE
- PeriodType attribute value: nf
- There is one version of the data. The records are not propagated and an upload is required for every forecast period.
Non-forecasted, propagated
- WDDDRIVER dimension attribute PropagateValues value: TRUE
- PeriodType attribute value: nf
- There is one version of the data. The records are propagated to all forecast periods and a new upload is required only if there is a change in the source data. The data propagation is done in the ATT_WDCDRIVER table.
Forecasted, propagated:
- WDDDRIVER dimension attribute PropagateValues value: TRUE
- PeriodType attribute value: f
- There are multiple versions of the data. The records are propagated to all data versions in the ATT_WDCDRIVER table. Every new upload changes the records in the current version and following data versions. The previous data versions remain unchanged.

These are the supported driver upload types:

Additive. The upload adds new records if the data area is different to the original upload. Or, overwrites the values for existing records if the data area of the new upload is identical to the original upload.
Replacement. The upload removes the existing records and replaces them with the new records. The replacement is always done for the driver's context. The full context differs depending on the driver type.

The different impact on records in the WDCDRIVER cube is described if new upload is done for:
