**Location Tree**
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
**For the new implementation**
|
||||||
|
|
||||||
|
We can now add locations like the tree above. First level is 'Stocks' representing all stocks the company has. Right now, our system only supports 1 Warehouse at the moment so every locations that we add will be under Warehouse.
|
||||||
|
|
||||||
|
Add New Locations Rules:
|
||||||
|
|
||||||
|
1. Warehouse as a default parent location
|
||||||
|
2. If location type pickable then discrimator map is 'pick-location' otherwise it will be on type 'qc-location'. The 'qc-location' allocating correctly when move items on non pickable locations.
|
||||||
|
2. Added ability to add location description.
|
||||||
|
|
||||||
|
**SKU Widget Enhancement/Fixes**
|
||||||
|
|
||||||
|
There are several discrepancies on the total stocks and allocations scenario. To address the issues we implemented the following:
|
||||||
|
|
||||||
|
1. We should list down all locations even stocks on retail shipments and retail direct orders or B2B Direct orders shipments.
|
||||||
|
2. Allocations should list down consolidated retail shipments, direct orders and non-pickable stocks allocation.
|
||||||
|
|
||||||
|
|
||||||
|
**Moving of stocks**
|
||||||
|
- By default we prevented moving of stocks in locations 'Stocks' and 'Warehouse'.
|
||||||
|
|
||||||
|
Additional features also added to edit location name and description except locations 'Stocks', 'Warehouse' and 'Picking Area'. Picking area is systems default pickable location it is hardcoded anywhere in the code. As per Rob, we should get rid of this location moving forward.
