Harbor Service reviews work orders before assigning its next shift. A positive amount does not necessarily mean that the work order is open, and an unassigned team is an exception even when the amount is zero. Apply the condition stated in each request rather than borrowing the last filter you used.
The file includes padded notes, null notes and an explicit empty string. Preserve those differences until the task gives you a replacement policy. You will also create typed fields and guard a division against zero. Inspect the output type along with its values. These tasks combine earlier preparation skills on a fresh extract, and the hidden records change the threshold cases so a copied sample answer cannot stand in for the rule.
