In the Basic List Line Structure screen, you determine the totals fields to be displayed using the options Totals and Counter.

The Total option calculates the grand total of a specified numeric field. This means that each time the field is read in a dataset, the field’s value is added to the sum total. The grand total is displayed at the end of the basic list. With control levels, you can also display subtotals. A subtotal contains all values of a field that are assigned to a particular control level, that is, a particular sort string.

Special Features:

• If you are totaling a particular field, the total is output in the same column as the field, that is, with the same output length. For this reason, the output length may be too short for the total and cause overflows. ABAP identifies these overflows by placing an asterisk in front of the affected value in the output.

• If you total values using a field that contains amounts in different currencies, the totals are created according to currency.

• The same applies to quantity fields. If you specify summation for a quantity field, this is performed according to the units involved and results in a distribution in the total lines.

The Counter option causes the counter number for a particular field to be increased by 1 every time that this field is found within the data set currently being read. The resulting counter total is displayed in much the same manner as a grand total at the end of the basic list. Just as with sum totals, counter subtotals can be displayed for individual control levels. These counter subtotals show how many values have been assigned to a particular control level.
