Hi;

first thanks for your help 

i tried to set up alternative work station before, it much better but using alternative routes leads to major deviations in the whole planning. it cause to a fragmentation of the plans. products have different start and end times.

I guess there is no other option but manual adjustment.

Hi,

In manufacturing, it's common for different products to share the same work center, but it can be tricky to know which ones are available. With Odoo, you can set up backup work centers so that if one is busy, it automatically shifts the work to another available one. This makes your manufacturing process more efficient by using work centers optimally. As the main work center is engaged and the capacity is exceeded, the alternative work center will be chosen to execute this manufacturing order.

Hope it helps
