Setting up negative inventory

Activate the negative inventory concept
In the Inventory Handling Parameters (whinh0100m000) session, select the Negative Inventory check box.
Default values for item types and item groups
Specify the required value in the Allow Negative Inventory field and select or clear the Create Outbound Advice Despite Inventory Shortage check box in the Item Warehousing Defaults (whwmd4501m000) session.
Default values for items
In the Item - Warehousing (whwmd4500m000) session, specify the required value in the Allow Negative Inventory field and select or clear the Create Outbound Advice Despite Inventory Shortage check box.
Default values for items by warehouse
In the Item Data by Warehouse (whwmd2510m000) session, specify the required value in the Allow Negative Inventory field and select or clear the Create Outbound Advice Despite Inventory Shortage check box.
Allow or block outbound advice for negative inventory
To allow or block the generation of outbound advice for negative inventory, select or clear the Create Outbound Advice Despite Inventory Shortage check box in the Process Outbound Advice (whinh4200m000) session or the Generate Outbound Advice (whinh4201m000) session.

Clearing the Negative Inventory check box when negative inventory is present

If you clear the Negative Inventory check box in the Inventory Handling Parameters (whinh0100m000) session when negative inventory is still present:

New outbound advice for negative inventory cannot be created.
The negative inventory records remain and are updated with received inventory. The application removes these records when the received inventory equals or exceeds the negative inventory.
The negative inventory settings in the Item - Warehousing (whwmd4500m000) and Item Data by Warehouse (whwmd2510m000) are not changed.

Note:

If the Create Outbound Advice Despite Inventory Shortage check box is cleared, you can still manually create outbound advice using the Outbound Advice (whinh4525m000) session in case of inventory shortage.
If the value of the Allow Negative Inventory field is Yes or If on Order and the Create Outbound Advice Despite Inventory Shortage check box is selected in these sessions, but the Negative Inventory check box is cleared in the Inventory Handling Parameters (whinh0100m000) session, no negative inventory is created.
