View, filter, lock and reschedule individual operations on the Gantt.
Every work order (operation) appears as a coloured bar on a resource row in the Gantt. Bars are sized to their planned duration and positioned in absolute time. Non-working hours are striped out per resource calendar.
Each Gantt bar is coloured by its manufacturing order, not by status. APS hashes the MO number into an 8-colour palette so that ops belonging to the same MO share a colour and you can trace them across the chart at a glance.
Operation status is shown as a badge in the right-side inspector when you click a bar:
On the Work Orders table, an operation with a slot on the calendar reads Ready only when its order's material is there. If the order is short or still waiting on a delivery it reads Planned instead: the work has a date, but it cannot be started yet, and the material column says why.
Late operations and conflicts (capacity overload, material shortage, dependency violation) are surfaced in the conflict list above the Gantt and in the inspector — not as a bar colour.
Grab any unlocked bar and drag it horizontally to change its start time, or vertically onto a compatible resource. APS validates the drop — if the new slot would break a dependency or exceed capacity, the bar snaps back and shows a tooltip explaining why.
Locked operations have a small lock icon and can't be dragged. Unlock from the inspector panel on the right.
Click any operation to open the inspector, then Lock. A locked op:
Use locks for: machine-specific setups, certified-operator-only work, or any decision the scheduler shouldn't overrule.
Open Work Orders from the sidebar to see all MOs in a table. Filters available:
By default the table shows only root MOs (top-level) and groups child sub-assemblies under their parent. Sort by any column — the sort persists across navigations until you change it.
Priority is set at the MO level in Odoo. A parent's priority is inherited by all child sub-assemblies during scheduling. To push an MO ahead, change its priority in Odoo (or in APS for the duration of a scenario).
See Materials for how priority interacts with FIFO supply allocation.
