Sage 100

Did Sage really drop all the user id fields from legacy invoice history? I see no complaints or suggestions. How to recover this data? For my 3.71 to 4.40 client I guess I can't import into the Last User Updated field without the business object platform overwriting it back to the user id of the importer. Catch 22?

I guess I wasn't clear - surely others are having the issue were a conversion of A/R from a legacy platform drops all of the user ids associated with the A/R History header. What am I missing here? Aren't other clients screaming about losing all the user ids that created an invoice prior to the upgrade? The System Information tab lists the creating user as blank and the modifying as the user doing the conversion. Help!
