The user is encountering the following error message when attempting to cancel the return sales order:
/The items are Purchased, Received, or Registered. Quantity ordered cannot be reduced because there are not enough open inventory transactions with the ordered status./
Upon investigation, we identified that the user had reserved a quantity greater than the posted sales invoiced quantity. However, when we attempted to recreate the scenario in the DEV instance, the system did not allow us to reserve more quantity than the sales order invoiced quantity.
Additionally, we are facing difficulties canceling the reservation, further complicating the resolution process.
Consequently, we are unable to regenerate the scenario and troubleshoot the issue in the development environment.
