Why can’t UNDP identify who sent the advance?
The Donor Code (given to the UN Secretariat by UNDP) of the UN entity paying the advance should have been entered in both the reference field and text field of the FV60 document. The remittance advance, which is automatically emailed to UNDP (email@example.com, firstname.lastname@example.org, email@example.com, and firstname.lastname@example.org) when the payment is made by the Treasury Division, contains the text field on the vendor line. UNDP use the Donor Code to identify who sent the advance.
If this information has not been entered when raising the FV60 document (as per UNDP job aid 2-0, then UNDP will not be able to establish which entity sent the funds.
