If you work on Atlas, check the three small dots to the right of the line(s) you want to delete. Then click the Delete Items button. If you work in SAP GUI, click the cursor to the left of line number for the line you want to delete. Then click Edit/Delete item. When you click Document/Complete, for each deleted line you will receive a Warning Message (in yellow): Amount is zero-line item will be ignored. SAP will leave the line as a marker, will zero out the dollar amount and will delete the line completely at the time the document is posted.
