Final answer:
The SF 1179 documentation is distributed at the right end in a disbursing officer's financial and retained returns, as it includes reports such as losses or discrepancies in shipments.
Step-by-step explanation:
The SF 1179, or the Government Losses in Shipment Report, is a form used by disbursing officers to report any discrepancies between shipments received and the accompanying billing documents. In the context of a disbursing officer's financial and retained returns, the SF 1179 documentation would be distributed on the right end. This is because the right end typically holds finalized documents that originate from the disbursing officers as part of their financial reporting responsibilities. This can include but is not limited to reports of loss, shortage, or damage of government property in transit which the SF 1179 details.
