Handling Amount Values in BW for Specific Currencies
SAP stores amount values of different currencies with a fixed interpretation of having two decimal places. There are some currencies that do not work well with such two decimal place setting. Usually this is because for some currencies, a fraction of currency unit is meaningless. That is true for the Japanese Yen, the Turkish Lira, and Korean Won and many other such currencies. In some cases, people want to store currencies with more than two decimal places for precision. How SAP handles such currencies (having entry in TCURX table) in BW is explained in details in this document.
