The first element of a shipment is an incoming sales order, as shown below:
​

Here, we can see that the quantity ordered = 20 and the shipment file has been created in the target location.
​
To create an error, we will edit the ship quantity within the file, as shown below:
​
​

This will create the "Part Undershipped" error, below:
​
​

To fix this issue, we must make two adjustments, the order in which these adjustments are made is not important.
The original shipment file must be edited to the correct ship quantity and placed back into the target location, as shown below:
​

For the purposes of this test, we used a target location within the local system. The target location in practice will likely be an FTP location, however, the process remains the same.

The errored shipment must also be deleted from the invoice review screen, as shown below:
​

The shipment can be deleted by loading the individual shipment (in this case order 943445) and clicking the red "X".
​
Once the corrected file has been placed back in the target location and the errored shipment has been deleted, the file can be reprocessed to success - shown below:
