If the tool has the tool type Assembled or Fictitious, this section appears. The table in this section adds all the sub-tools with the quantity that belongs to the tool set.
If it is a fictitious tool (tool type), this is the only section active under this tab, since this fictitious tool does not physically exist.
If it is an assembled tool (tool type), you can also enter other general information for the tool. Assembled tools physically exist and have their own stock location.
