Since we upgrade the OE to 8.1 from 8.0, the history of the detail items transactions disappeared from the OE history. Please let me know how I can fix it.

Thanks,

Did someone purge the history? Nothing about the installation of the new version changed anything being stored in the files.

You mentioned in another forum posting that a problem started when a 'franchises' custom modification was put in. Could that have any influence over what is happening here?

Does your data pass an integrity check? If details indeed went missing, you would see errors reported.

No, this is happen before we install the custom modification. When we test the integrity, there would be errors on the history of OE. However, when we went to Accpac plus, we can view the history details fine. Should there be an error on the new version?

ACCPAC Plus doesn't have an order history (although there was a product that did this from Softline). Did you convert those historical orders into Adagio OrderEntry?
