**Impacted versions:** 8.0

**Steps to reproduce:**
To reproduce it is necessary the fifo configuration in the assignation of quants in moves.

- Create a sale order with two lines of the same product, one of that line with a route that generate moves between warehouse.

The route used has three pull rules:

1. From Stock Warehouse_1 to Virtual Locations/Inter Company Transit
2. From Virtual Locations/Inter Company Transit to Stock Warehouse_2
3. From Stock Warehouse_2 to Customers

- Confirm the sale order. It must be created three pickings:

- Transfer first two pickings.

- Before transfer third picking, review that one move has reserved the quant correctly because was reserved from the previous pickings.

**Current behavior:**

When check availability of this third picking, the quant already reserved is moved to the other move.

**Expected behavior:**

When check availability of this third picking, the moves already reserved must not be altered.
