  8. Enter 1 as Actual Value
  9. Choose on Next and then Finish.

Now that there is a positive inventory of the product, so the Scrapping can be performed:

  1. Go to Internal Logistics Work Center
  2. Choose the common task Scrapping
  3. Enter the Site ID ABC
  4. For the field Actual Execution On, enter the same date used as Key Date in the Inventory Adjustment
  5. Choose Next
  6. Select the Product XYZ and enter the Product Scrapped Quantity, this quantity must be the negative stock you want to enter plus 1. (i. e. If you want to enter a negative stock of -100, you need to enter 101 as scrapped quantity).
  7. Choose Next
  8. Choose Finish 
  9. Now you will have a negative stock in the selected location

Note: If the location does not allow negative stock, the system will return an error message during the Scrapping process as well.
