The logic for Negative stock

“Support negative” module:

was added to the system;
if the module is switched on -> it’s possible to make negative stock on Sale Order and POS Sale mode;
it’s possible to switch off negative if in the system there is no one negative transaction.

Sale Order / Ship Order edit form:

Negative substatus for order:
- if at list one item has linked negative transaction -> the substatus is displayed;
Negative substatus for line item:
- is displayed for items that have linked negative transaction;
- on SO/SHO first is displayed main item status then is displayed negative (color red);
- for example
  - SO: Ready to ship / Negative;
  - SHO: Shipped / Negative.

Negative transaction:

is deleted automatically:
- after clicking on the Delete line item / Unreserve line item / Void line item / Convert to Draft / Void Order / Delete Order / Close Order on SO;
- after Deleting Invoice:
  - if a negative was created for Not Reserved / Check Stock / Backorder items:
    - once Invoice has been deleted:
      - SHO has been unshipped (logic not change);
      - Sale Order the line item is moved to the previous status (for example Backorder item has Backorder status);
      - the negative transaction is deleted;
  - if a negative was created for an item with allocation type “Create Negative Stock Qty”:
    - SHO has been unshipped (logic not change);
    - Sale Order the line item is moved Not Reserved status;
    - the negative transaction is deleted;
is updated automatically:
- after making Increase item / Decrease Item.

Decrease Invoice with negative transaction:

If invoice was decreased and Ship Order -> is unshipped:
- SO/SHO are in negative substatus;
- SO/SHO line items are in negative substatus.

Ship Order edit form / Shipping Schedule / Shipping for e-commerce:

Create Negative Stock Qty for: Not Reserved / Check Stock / Backorder items:
- if item has one of such allocation types and module is switched on -> After clicking on the Ship button on SHO edit form / Shippings Scheduled / Shipping for e-commerce:
  - negative transaction is created for Not Reserved / Check Stock / Backorder items:
    - on Transaction History panel -> transaction is negative with Type = “OUT”;
  - SHO has “Negative” substatatus;
  - Line item on SHO will have status “Shipped” and substatus: “Negative”;
  - SO has “Negative” substatatus;
  - Line item on SO will have status “Shipped” and substatus: “Negative”;
Ship Qty field:
- if module is switched on -> it’s possible to enter ship qty more than available qty;
- If user enters Ship Qty > Available qty:
  - warning is displayed: “Negative Qty transaction will be created”.

Fix Negative Transaction:

Negative Transaction is deleted -> if IRC or Inv Adj were created by next rules:
- IRC or Inv Adj were created to stock same as SO;
- item qty is not linked to any order;
- item qty is not less than qty on SO;
once order has been created by previous rules -> the negative transaction is deleted and instead of it, the new IRC or Inv Adj partially or fully is linked to SO;
once new positive transaction linked to SO:
- negative substatus is deleted from SO/SHO;
- negative substatus is deleted from line items on SO/SHO.
