When Price index is defined in the master data of a bond (tcode FWZZ, Basic data tab), sometimes it is not clear how the system calculates the position amount for interest flows. I would like to explain it with an example.

Price Index definition, see customizing:

Financial Supply Chain Management >  Treasury and Risk Management > Basic Functions > Market Data Management > Master Data > Indexes > Define Price Index (table TIDX_PRICE_INDEX)

Index Values are defined in customizing:

Financial Supply Chain Management >  Treasury and Risk Management > Basic Functions > Market Data Management > Manual Market Data Entry > Securities and Indexes > Enter Price Index Values (tcode S_KFM_86000134)

Bond position is created and the cash flow is as below (TPM40):

How does system calculate the Amount in position currency for the interest flow with position value date 01.06.2005) ?

It takes the calculation date as value date, in this case it is 30.05.2005.

1) System will find the related low and high index comparing to this value date:

wa_priceValueLow

VALUE_DATE   20050515  INDEX_VALUE  115.000000

wa_priceValueHigh

VALUE_DATE   20050615  INDEX_VALUE  125.000000

2)  Get the number of days between the low and high index values:

20050515 ~ 20050615, no.of days 31

3)  Get the number of days between the low index value and the value date:

20050515 ~ 20050530, no.of days 15

4)  Do the interpolation:

CALL FUNCTION ‘FIMA_INTERPOLIEREN’    EXPORTING                    I_X1          = 0          I_X2          = nDaysBetweenLow_High                    I_X3          = nDaysBetweenLow_ValDate          I_Y1          = IM_LOW_INDEX_VALUE-INDEX_VALUE          I_Y2          = IM_HIGH_INDEX_VALUE-INDEX_VALUE     IMPORTING          E_Y3          = floatIntPolIndexValue

E_Y3 = WRK_Y1 * ( WRK_X2 – I_X3 )

+ WRK_Y2 * ( I_X3 – WRK_X1 ).

WRK_Y1    1.1500000000000000E+02

WRK_X2    3.1000000000000000E+01

I_X3      15

WRK_Y2    1.2500000000000000E+02

I_X3      15

WRK_X1    0.0000000000000000E+00

-> E_Y3      3.7150000000000000E+03

Then E_Y3 = E_Y3 / ( WRK_X2 – WRK_X1 ).                   = 3.7150000000000000E+03 / (3.1000000000000000E+01 – 0.0000000000000000E+00)                   =  1.1983870967741936E+02 (float Intpol Index value)

5)   Do the rounding

1.1983870967741936E+02 equal to 119.838710000000

tmpIndexInRatio     1.1983871000000001E+02tmpRatio                  1.0040000000000001E+02 (Ratio 100.40)

* Index value in No ratio  indexNoRatio    = tmpIndexInRatio / tmpRatio.

= 1.1983871000000001E+02 /  1.0040000000000001E+02                            = 1.1936126494023904E+00

a. index value in Ratio is rounded to 6 decimals:  119.838710;

b. Check the size of the base ratio, if it is between 100 and 1000 (in this case 100.40),  we add TWO more decimal than the rounding rule states, the real ratio would be rounded to 8 decimals: 1.193612650000.

6)  multiply the position currency amount with the index value

-index_value =   l_index_value. multiply -position_amt by l_index_value.

-index_value  is 1.193612650000

Position amount of interest flow without index (index-clean) is 53000.00.

You will get the position amount of interest: 53000.00 * 1.193612650000 = 63261.47

Hope this helps to understand the calculation logic.
