By default, the ageing report displays the Business Partner (BP) balance according to the 'Business Partner' currency, as defined in the Business Partner Master Data. When a BP is defined as having 'All Currencies' (2005A: Multi Currency), then that BP's operative currency is the local currency of the company.
