What is the problem pls help me.

Have you checked ROUNDING.TYPE and/or BASE.ROUND.TYPE for currency USD ?

Hi armin,

I check in currency record of USD found only:
28 Min Round Type
29 Cash Round Type

set as 1 : Natural rounding
Could you please explain me more?

Sorry, was offline for some days :(

The fields mentioned are in TAX (15 and 17) and can be set up by currency, but look like you dont use it (haven't had a close look to your first post, sorry).

The setting in CCY seems OK, natural rounding means mathematical rounding to MIN.ROUND.AMOUNT.

Have you checked if there is INTEREST.TAX.MIN defined in your GROUP.CREDIT.INT ?

Alternatively you can set ROUNDING.RULE in TAX to point to a alternative EB.ROUNDING.RULE. E.g. set up TAX.UP in EB.ROUNDING.RULE to use ROUND.TYPE = 3 and use it in your TAX definition.

HI ALL,

Can anybody explain the use of ROUNDING.type and BASE.ROUND.TYPE?

Thank you

Thanks
