module EDI::S

Notes:

SEDAS data are organized as record sets. A physical file or transmission unit is always framed by record types 00 and 99. Within such a physical unit, one or more logical units may occur, framed by records 01 and 98.

SEDAS data are self-contained already at the message level. An “Interchange” of the SEDAS type is just a concatenation of messages; a single message per Interchange is quite acceptable. However, one such message will usually map to several messages of the UN/EDIFACT type. As an example, a sequence of record types 29 may map to one or several INVOIC messages (BGM+393), depending on the number of group changes (document number changes).

Also note that SEDAS record types 50, 51 are considered master data. They are referred to by earlier records to avoid redundant data. Here we treat this master data block as a single “message” - but not with mapping in mind.

Here we use the Interchange level only to maintain the information about the physical/logical unit data.
