Use PPNO to calculate the previous payment number for loan with regularly scheduled periodic payments.

SELECT [wctFinancial].[wct].[PPNO] (

<@SettDate, datetime,>

,<@FirstPayDate, datetime,>

,<@pmtpyr, int,>

,<@NumPmts, int,>)

the date from which you want to calculate the previous payment number. The previous payment number is always associated with the maximum payment date less than or equal to *@SettDate*. @*SettDate *is an expression of type **datetime** or of a type that can be implicitly converted to **datetime**.

the date that the first payment is due. @*FirstPayDate *is an expression of type **datetime** or of a type that can be implicitly converted to **datetime**.

the number of loan payments made in a year. *@NumPmts* is an expression of type **int** or of a type that can be implicitly converted to **int**.

the total number of payments to be recorded over the life of the loan. *@NumPmts* is an expression of type **int** or of a type that can be implicitly converted to **int**.

float

· If*@SettDate* < *@FirstPayDate*, NULL is returned

· *@Pmtpyr* must be between 1 and 365

· If *@Pmtpyr* = 13, then payments are calculated every 28 days from *@FirstPayDate.*

· If *@Pmtpyr* = 26, then payments are calculated every 14 days from *@FirstPayDate.*

· If *@Pmtpyr* = 52, then payments are calculated every 7 days from *@FirstPayDate.*

· If *@Pmtpyr* = 1, then payments are calculated every 1 year from *@FirstPayDate.*

· If *@Pmtpyr* = 2, then payments are calculated every 6 months from *@FirstPayDate.*

· If *@Pmtpyr* = 3, then payments are calculated every 4 months from *@FirstPayDate.*

· If *@Pmtpyr* = 4, then payments are calculated every 3 months from *@FirstPayDate.*

· If *@Pmtpyr* = 6, then payments are calculated every 2 months from *@FirstPayDate.*

· If *@Pmtpyr* = 12, then payments are calculated every 1 month from *@FirstPayDate.*

· If *@Pmtpyr* = 24, then payments are calculated every semi-monthly from *@FirstPayDate.* If the *@FirstPayDate* is the 15^{th} of the month, payments are on the 15^{th} and the last day of the month. If the *@FirstPayDate* is the last day of the month, then payment dates are on the last day of the month and the 15^{th} day of the month.

· If *@NumPmts* IS NOT NULL, then PPD will not return a payment number greater than the number of payments.
