Yes, this is possible using Odoo's Work Centers with the "Workcenter Capacity" feature and configuring Work Orders without a specific workcenter line assignment. Here is the recommended setup:

1. Create one Work Center per station type (e.g., Assembly Station, Finishing Station) rather than per physical line. Set the Capacity to the number of parallel lines (e.g., 3 for 3 assembly lines).

2. In your BoM Work Orders, assign operations to the Assembly Station and Finishing Station work centers (not to a specific line). Workers scan products at any physical station that belongs to the same Odoo work center.

3. In Shop Floor, workers see the work center queue. They click the operation for a product, complete it, and the step is recorded. The physical station/line does not need to match - only the work center type matters.

This way, any of your 3 assembly lines can process any product, and workers only scan the product barcode (not a work order barcode) at the station type they are working at.
