When viewing the XML file for 'sc_req_item' records some fields may appear to have multiple values.
(Administrators can view a records XML file by right clicking on the header and selecting 'Show XML'.)
For example, users may notice two sets of 'sys_created_by'/'sys_created_on' and 'sys_updated_by'/'sys_updated_on' fields that have different values.
This is expected functionality as the second values belong to related 'fx_price' records.
These are used by the platform to calculate catalog item costs.
You can see the second set of values are for Price records because they are defined within '<fx_price>' & '</fx_price>' tags around the bottom section of the file.
