Conversion Utilities; now allow Fixed Term Loans to amend the Loan Maturity date

Whilst converting, Fixed Term Loans now allow the Loan Maturity date to be amended.

The finAccount.SupportsMaturityDateChanges property now returns True if the Account is a Fixed Term Loan Account and the Business Layer is set to conversion mode, i.e. finBL.ConversionUtilities.IsConverting is True.

This means the finAccountMaturityDateChange object can be used to amend the Maturity date for a Fixed Term Loan Account. Note, the AuthorisedName and Reference properties should be set to something like "Conversion".
