I have some doubt regarding internal pickings and ougoing...
At the moment, if the lot exists and not in sml reserved, the stock move line is created, but I don't check if there is availability...

@ryanc-me #1062 fixed here

@sergio-teruel Looks good! I hope you don't mind my feedback below.

You make a good point regarding the availability check. Maybe one of these would work:

1. If the stock is not available, display a pop-up wizard showing the unavailable lines, and offering to Confirm or Cancel
2. Add an option to the initial import wizard (or company settings) so the user can choose whether to consider/ignore stock (e.g. "Check Availability" boolean field)
3. Ignore availability all together - this is an explicit import, much like entering SMLs manually via the detailed operations tab, so perhaps the user intent is to "import exactly what I say"?

Lastly, I think the availability-check logic should apply to incoming transfers also: If we have an inter-warehouse receipt, the picking type usage may be incoming, but the source location could actually be tracking stock (like WH/Stock -> Transit -> WH2/Stock, the last step is a receipt but we do know what stock is in Transit)

Maybe the location_src_id.usage field is a good check instead? (i.e., ignore availability for any "Virtual" locations)
