Hi,

In your furniture manufacturing setup using Odoo, you're dealing with a multilevel bill of materials where each part—such as side panels, tops, and backs—requires sequential operations like cutting, drilling, and sanding. While you've set work dependencies within individual components (e.g., drilling follows cutting on a side panel), Odoo's standard MRP system treats identical operations like "cutting" across all parts as parallel tasks. This means when the production order is generated, all cutting operations for every part are made available at once, without enforcing a global priority or sequencing across the entire furniture unit. As a result, it becomes difficult to manage the workflow on the shop floor where, in reality, your cutting machine can only process one part at a time based on its unique dimensions. This leads to operational confusion and lack of prioritization. To solve this, you'd need to implement either a custom scheduling mechanism, operation-level sequencing that spans all components, or use a planning tool or custom Gantt chart that groups and prioritizes operations based on part and work center constraints, ensuring a more realistic and organized execution plan.

Please refer to the following links:

Hope it helps.

 Use Sub-Assemblies with Separate MOs

Instead of having one large MO with a nested multilevel BoM:

• Split your furniture into logical subassemblies: e.g., Side Panel, Drawer Front, Top Panel, etc.
• Each subassembly should have its own BOM + MO, with its own operations.
• This gives you clear separation and control over the operations.

Benefit: Now “Cutting for Side Panel” and “Cutting for Drawer Front” are separate work orders.

Example

Let’s say you have a furniture item with:

• Side Panel (needs Cutting → Drilling)
• Drawer Front (needs Cutting → Sanding)

Instead of one massive MO:

• Create 2 MOs:
  • MO#1: Side Panel
  • MO#2: Drawer Front

Each has its own:

• Work orders (Cutting, Drilling, etc.)
• Priority
• Scheduling
• Work instructions

Now your cutting station sees:

• WO#1: Cut Side Panel (Due today)
• WO#2: Cut Drawer Front (Due tomorrow)
  
  And one more thing , Work dependencies set at the component level are not respected globally across the multi-level MO.
  
  I hope this helps you.
