Option 1: Customization – Add Work Center-Specific Instructions

You can customize the mrp.routing.workcenter (aka Operation lines in Routing) model to include work center-specific instructions. Here's a high-level outline:

1. Add a One2many field on the operation to store multiple instructions:
class MrpRoutingWorkcenter(models.Model):

    _inherit = 'mrp.routing.workcenter'

    instruction_ids = fields.One2many(

        'mrp.workcenter.instruction', 'routing_wc_id', string="Work Center Instructions")

Create a model for mrp.workcenter.instruction:
class MrpWorkcenterInstruction(models.Model):

    _name = 'mrp.workcenter.instruction'

    _description = 'Work Center Specific Instruction'

    routing_wc_id = fields.Many2one('mrp.routing.workcenter', string="Routing Operation")

    workcenter_id = fields.Many2one('mrp.workcenter', string="Work Center")

    instruction = fields.Html(string="Instruction")

Update your views to allow editing instructions per work center.

Modify the work order UI or PDF report to show the correct instruction based on the work center.

Option 2: Duplicate Operation with Work Center-Specific Routing (Less dynamic)

• Create two separate operations in the routing:
  • "Cutting - Machine A"
  • "Cutting - Machine B"
• Assign the appropriate work center and instructions for each.
• In the BoM, choose the correct routing depending on which machine is used.

This option is easy to implement but not as scalable if you have many overlapping operations.
