I changed the GL account of a shipping item, not realizing it affected history- oops. When I did, it had an X amount decrease in the original account but a 2X increase in the new account. Invoices simply had the credit amount changed between the two accounts, but for some reason Item Fulfillments now show a credit for that shipping amount too when before there was none. Any ideas why this is? Changing the GL account back leaves the credit there, just now with the original account. How can I reverse this? Has anyone run into this problem before?
