We do not use CSC for authentication. We have not been able to test how other CC declines will impact the order. At this point we plan to make a copy of the cancelled order and attempt to reauthorize it. Thank you for your help

I followed your example of adding one and deleting one item. It added an Average cost to the location but not at the header level of the item. Does this update, if so when? I have refreshed the page several times and the header level average cost is still blank.
