  5. Verify that only standard planned items on the top level of the standard structure are included in the procurement list, i.e., 20–120 (Cylinder Head 1600).

  6. Verify that the correct required quantity has been calculated for each project item.

  7. Look at the required date for each of the second-level standard planned project items. Note that this date is the early finish date of the project activity connected to the top project item minus its manufacturing leadtime.

  8. Look at the required date of each project-specific project item 20–11XX (Engine Block 1600) and 20–10XX (Engine 1600). This date should reflect the early finish date of the activity connected to the item.
