In some cases, replanning a work order does not change anything.
To reproduce the issue:
(Use demo data):
1. In Settings, enable "Work Orders"
2. Create two manufacturing orders (MO01, MO02) with 1 x [FURN_8522]
Table Top
3. Confirm MO01 and MO02
4. Set the same Scheduled Start Date (SSD) on the WO of each MO
- A warning should be displayed on the work order line because of
the conflict
5. Open the warning and click on "Replan"
Error: Nothing happens, the warning is still displayed and the scheduled
start date does not change.
For the warning symbol to be displayed, we check (through
`_compute_json_popover`) if two work orders are in conflict:
https://github.com/odoo/odoo/blob/8cb5aad6126e3f63ee4ef91115c8b4a6be571828/addons/mrp/models/mrp_workorder.py#L719-L722
So, we base this information on the `mrp.workorder`
However, the planning logic is based on another model:
`resource.calendar.leaves`. When planning a WO, we create a
`resource.calendar.leaves` and we link this slot to the WO thanks to the
field `leave_id`:
https://github.com/odoo/odoo/blob/4870606b00a758e63713e6e82c0cba9b1e7dd4aa/addons/mrp/models/mrp_production.py#L1238-L1248
Therefore, when replanning a WO, we ensure that the new slot does not
overlap any existing slot in the same workcenter. But, here is the
issue: when writing the start date (step 4), we try to replan the WO of
the MO only if this MO is already planned:
https://github.com/odoo/odoo/blob/4870606b00a758e63713e6e82c0cba9b1e7dd4aa/addons/mrp/models/mrp_production.py#L723-L724
Wich is not the case in the above steps. So, we don't (re)plan anything
=> we don't create any slot.
As a result: the warnings are displayed, which is correct, but when
trying to replan one of the WO (step 5, viathanks to
`_plan_workorders`): There isn't any slot starting from WO's start date
(there isn't any slot at all!), so we can create a new slot -> the start
time of the WO does not change -> considering their start times, there
is still a conflict between both WOs.
Comment: if after the step 5, the user tries to replan the other WO, it
will work: the first replanning fails but a slot has still been created.
Therefore, when replanning the second WO, the newly-created slot will be
detected, a second slot will be created after the first one and the
start date of the second WO will be postpone (according to the second
slot).
(!) Note that nothing creates any slot if we directly define the start
time of the WO during the MO creation (step 2). So this use case will
fail too.
We should ensure a perfect coherence between both models
`resource.calendar.leaves` and `mrp.workorder`.
