Hi Lulu,

In the AP company profile on the System/Report options tab is a setting for 'Keep transaction history for X days'. Whatever value you enter for X will determine how old historical transactions must be in order to be purged.

Payables versions 8.1A and older have a maximum of 999 days (or about 3 years). In version 8.1B the maximum was increased to 9999 days (or about 30 years).
