2. Click New DataMapper Configuration.
3. From the Using a wizard pane, select Generate counters.
l From the File menu
1. In the menu, click File > New.
2. Click the Data mapping Wizards drop-down and select Generate counters.
You can set the following parameters:
l Starting Value: The starting number for the counter. Defaults to 1.
l Increment Value: The value by which to increment the counter for each record. For
example, an increment value of 3 and starting value of 1 would give the counter values of
1, 4, 7, 10, [...]
l Number of records: The total number of counter records to generate. This is not the end
value but rather the total number of actual records to generate.
l Padding character: Which character to add if the counter's value is smaller than the
width.
l Width: The number of digits the counter will have. If the width is larger than the current
counter value, the padding character will be used on the left of the counter value, until the
width is equal to the set value. For example for a counter value of "15", a width of "4" and
padding character of "0", the value will become "0015".
l Prefix: String to add before the counter, for example, adding # to get #00001. The prefix
length is not counted in the width.
l Suffix: String to add after the counter. The suffix length is not counted in the width.
