Hi guys !

I'm a beginner to automated actions in Odoo and I've an error in my python code and can't understand why this is happening (no report). 

I would like all times, for the same operation name, to be set to the trigger which is the update of one of the times.

Here is my code :

model : mrp.routing.workcenter

trigger : on update value

trigger field : manual duration

A = record['time_cycle_manual']
NOM=env['mrp.routing.workcenter'].search([('name','=',record.name)])

for rec in NOM :
    rec['time_cycle_manual'] = A

I'd appreciate if you could spend some time to help me, thanks !
