To reproduce the issue:
(Use demo data)
1. In Settings, enable "Multi Locations"
2. Create a storable and tracked-by-lot product P
3. Create an immediate receipt R
4. Add a line for 1 x P and save
5. Open the wizard 'Detailed Operations' and add a line:
   - 1 x P, lot 123, to WH/Stock/Shelf 1
6. Save
7. Open the wizard again

Error: The destination location of the line is now WH/Stock

When creating the SML, because we write on its done quantity, we
will automatically write the same on the new done quantity of the SM
on the demand of that SM. Doing so, it will trigger the assign
process:

(And it will therefore lead to the putaway rules feature)

Once the above issue is fixed, there will be another one. When
marking the SML as done, if it's needed, we assign it a lot. However,
writing on such a field will trigger the reservation process:

And it will lead, again, to the putaway rules feature
