Answer a named premium amount query

Any consumer needs a named premium figure (standard, discounted, estimated, NEAP, …)

Field	Value
Operation ID	OP-005
Trigger	Any consumer needs a named premium figure (standard, discounted, estimated, NEAP, …)
Inputs	An IPremiumAmountProvider (e.g. clsPremiumSet) and a PremiumAmountTypes value (26 members)
Outputs	A decimal premium amount
Primary components	PremiumAmountProviderExtensions.PremiumAmount(provider, type) (iPremiumAmountProvider.vb)
Entry point	Business\SAIF.Business.Policy.Premium\iPremiumAmountProvider.vb

Steps

1. Obtain the provider's sub-total list (OP-004).
2. Select the sub-totals whose type matches the requested PremiumAmountTypes value.
3. Sum DifferenceAmount across the matches — except for the NEAP type, where BaseAmount is summed instead (BR-016).
4. For the Discount amount, return Discounted amount − Standard amount (BR-017).
5. Return zero when no sub-totals match.*
