Forwarded email — 850 purchase order

A purchase order pasted straight out of a forwarded email: an email header sits before the ISA, four ISA elements were trimmed below their fixed width, and IEA01 claims two functional groups when there is one.

Envelope

Sender	ZZ / NORTHWINDFrom ISA05 (qualifier) and ISA06 (ID).
Receiver	ZZ / CONTOSOFrom ISA07 (qualifier) and ISA08 (ID).
Usage indicator	PISA15 — P = production, T = test, I = information.
Interchange version	00401ISA12 — the interchange control version number.
Date / time	240401 0915ISA09 and ISA10 — when the interchange was prepared.
Functional groups	1GS segments counted while walking the payload; IEA01 is checked against this.
Transaction sets	1ST segments counted; each group's GE01 is checked against its own count.
Segments	10Total segments in the cleansed payload; each SE01 is checked against its set's count.

Repair passes

The Byte column is the offset into the submitted text where the flagged structure begins; ISA-line findings share a number, and a dash means the finding isn't tied to one spot.

ERROR	`isa.element-width`	88	An ISA element is not its fixed width ISA02 is 3 byte(s); padded with spaces to its fixed width of 10. Every ISA element has a fixed width -- ISA06 is 15 bytes, ISA13 is 9, and so on. This element was shorter (space-padded on the right to fit) or longer only by trailing spaces (trimmed). The value itself is unchanged. A sender that right-trims blank fixed-width fields is the usual cause. This is an error, not a warning: the ISA line is no longer 105 bytes, and conventional VAN services and fixed-offset parsers cannot read the interchange at all until it is repaired.

WARNING	`isa.leading-bytes`	0	Bytes precede the ISA segment 88 byte(s) precede the ISA segment (b'Subject: FW: Q1 reorder - please confirm\r\nFrom: purchasing@northwind-traders.example\r\n\r\n'); stripped before parsing. One or more bytes appear before the ISA segment. A conformant X12 file begins with 'ISA' as its very first byte. Common causes are a UTF-8 byte-order mark, whitespace, or transport headers left in by the sender. x12-tidy strips them and continues; the reported bytes are what was removed.
