average interest rate yield curve for bank overdraft account

[Former Member]

Is it possible to:

u2022 Define a yield curve for (monthly) average interest rate based on an reference interest rate that is entered daily.

u2022 in a function module read the value for this average interest rate that is in table JBD11

u2022 in the interest indicator customizing transaction OBAA assign the above function module

u2022 In the bank GL account assign the above interest indicator

Hi,

Interesting derivation though I haven't worked on this directly, technically this should work. But just a quick question, if you want the monthly average rate of the reference rate values entered for 30 days, you mean to say it is an average of all the values for the month? If that is the case, you need not define the yield curve at all.

You can estimate the par rate for a future date or a future period and find the discount factor for those days which can be used to determine the net present values of a future flow using the yield curve as the base.

But for your case, if it is just the average, pick the reference interest rate values and find the average in your function module itself. I dont see a need to use the yield curve.

Hi Ravi

I agree. In the function module SAP can calculate the average interest rate without referring to a yield curve. Just for maximizing the use of functionality in SAP I thought of use of the yield curve.

Would you know which standard SAP function module is available for this? (before we develop a custom function module on table Reference interest table T056P.
