It is used to process transactions for which the payment 

was received but the order was not submitted for processing.

A few known cases:

 1. Missing transfer price for an item

 2. Lack of AWB numbers

 3. Amount mismatch

 4. Payment was successful but the user was not redirected to

 our website.
