Mail Details Node
Bag No. is defined as - “Bag Number of Mail. Can be the UPU S9 identifier/ Receptacle ID”.
UPU S9 identifier denotes the 29 characters of the mail tag (Origin IMPC, Destination IMPC, Category, Sub Class, Despatch-year, Despatch-number, Receptacle serial number, Highest Numbered Receptacle Indicator, Registered/Insured indicator, Receptacle weight). This could indicate that the billing is at a mail bag level.
But the node also contains a mandatory tag ‘NumberofBags’, which would make sense if the billing is at a despatch level.
The sample file for mail (MXMLF-1112010030320110114130569.xml) available with the ISPG 3.2.1 release, displays 3-4 alphanumeric characters in the bag number field. E.g. 567, R123 etc. We could not relate this to the UPU S9 identifier.
Please advice the actual values that needs to be displayed in the Bag No. field.
Also do let us know, at what level are we expected to invoice mail – at despatch level or mail bag level?
Assuming, we as a billing carrier decide to do outward billing at despatch level. But, it could be possible that we receive the inward billing at a mail bag level. As a billed carrier the rejections raised by us will be at despatch level. Is that OK from an audit trail perspective?
Thanks for the response in advance.
