You can specify number formatting for the decimal and thousands separator characters. The system uses this number format for the data in data grids, and in data load and extract. During data load, the system uses the user-defined decimal point and thousands separator. For data extract, the system uses only the user-defined decimal point. You can use any characters for delimiters except Arabic numerals (for example, 0 through 9), an ampersand (&), and back slash (\).
