Problem Note 46321: Reverse prorate of cash flows cannot be performed

DetailsHotfixAboutRate It
In SAS® Risk Dimensions®, the prorating of cash flows refers to the fraction of a cash flow that is assigned to a specific time bucket. For example, the bucketing time grid is (30 day, 60 day) and one cash flow position with two cash flows (amounts CFAmt1 and CFAmt2) to bucket as described by the following portion of a PROC COMPILE method.
_cashflow_.n = 2; _cashflow_.matdate[1] = basedate + 10; _cashflow_.matamt[1] = CFAmt1; _cashflow_.matdate[2] = basedate + 40; _cashflow_.matamt[2] = CFAmt2;
The following picture helps visualize the cash flows relative to the bucket dates. The "Bucket Date 1" is the basedate; the "Bucket Date 2" is 30 days after the basedate; and the "Bucket Date 3" is 60 days after the basedate.
 
       Bucket               Bucket               Bucket 
       Date 1               Date 2               Date 3
         |                    |                    |
--------------------------------------------------------------> time
                |                    |                 
             CFAmt1               CFAmt2              
Bucketing these cash flows with standard prorating assigns 1/3*CFAmt1 to bucket1, 2/3*CFAmt1 + 1/3*CFAmt2 to bucket2, and 2/3*CFAmt2 to bucket3.

Bucketing these cash flows with reverse prorating assigns 2/3*CFAmt1 to bucket1, 1/3*CFAmt1 + 2/3*CFAmt2 to bucket2, and 1/3*CFAmt2 to bucket3.
