Why is the minus sign not displayed in the Document display (for example Transaction FB03)?
The minus sign is only intended for internal use, to distinguish between direct and indirect quotation. For external display, direct and indirect quotation are distinguished by a customizable prefix, which you can define in table TCURP (in Transaction OPRF). If you do not define the customizing in table TCURP, exchange rates are displayed as they were before – directly quoted exchange rates are displayed with no prefix, while indirectly quoted exchange rates are displayed with a “/” character to indicate the division. When converting amounts of foreign currency to local currency, the system divides by an indirectly quoted exchange rate and multiplies by a directly quoted exchange rate. From a technical point of view, the “EXCRT” conversion exit is appended to the exchange rate fields; its CONVERSION_EXIT_EXCRT_INPUT and CONVERSION_EXIT_EXCRT_OUTPUT modules control the change from an internal display using plus or minus signs to the external display using other prefixes.
