Hello Iata,
The SIS P3 - IATA IS XML Invoice Standard - V3.2 worksheet, under the 'Notes' tab, Row 40 defines '1-oo' as 'This implies that the field is mandatory and can occur multiple times'
If you look under the 'M&U Charge Category-ChargeCode' tab, 'MiscData @Name @UOMCode' has an Occurrence defined as '1-oo'. However, each charge code is listed as Recommended Always (RA).
We understand that Recommended Always means are fields that are recommended forever (P 94 of the ISPG v3.2). Therefore these fields are not Mandatory, nor will they ever become Mandatory (as they would then be Recommended and not RA fields)
So our question is this: How can the 'MiscData @Name @UOMCode' field be defined as '1-oo' (mandatory), yet for all charge codes, it's Recommended Always ??
Please advise as we are trying to decide if we should support the 'MiscData @Name @UOMCode' field.
Kind regards,
Brian.
