When you override the numeric separators or define the field width, the Designer shows the options you define in the Format column on the Columns tab. For example, you have a numeric column with a precision of five. Click the Format column and define the options in the Column Format Settings dialog box.
The following figure shows the format options the Designer displays in the Format column:
The Designer displays
N,NNN(F 6.5).NN
in the Format column for the PRICE column. “N,NNN” displays the thousands separator you specified. “F” indicates a fixed field width. This displays “A” when you adjust the field width. “6.5” is the field width and precision in bytes. The first number is the field width, the second is the precision. “.NN” displays the decimal separator you specified.
If you do not define decimal and thousands separators for a particular source or target field, the Integration Service uses the separators you specify in the source or target instance in the Mapping Designer.
