Adjustment in interest value calculation

Hi dear,

hope you are well.

I have a contract witch have a difference in interest value when to compare with the bank value, it is caused because the bank calculate the interest rate factor with 8 decimals and TRM uses more decimals.

I know that is possible to adjust it using the functions "rouding unit" and "base unit", but I don't know how those functions make the calculation, because the formula that show in performance assitant is not what the system do. Can you help me?

Thank you and best regards,

LuMaki

    Hi Luci,

    I don't think "Base unit" & "Rounding Unit" would help.

    Tx FIMA calculates interest upto 10 decimals. In some product Types interest decimals are upto 7 digits. In general difference with the Bank is because of interest methods and not decimals, only big numbers could make difference in decimals.

    Check sap notes

    Hi Gustavo,

    Yes, these fields helps, but I am using it by trial and error and I could reduced the difference from $ 32,64 to $ 0,88, but I need to reduce this difference to 0. This is why I need to know how these functions effectively works, or if there are other way to reduce Tx FIMA to 8 decimals.

    In my contract the problem is the decimals, I did the calculations to prove it.

    Can you help me?

    Kind regards
