AMAZON EDI / required payer name in NAD+IV segment is longer than 35 character limit - sap

Question

I am working for a big manufacturer and supplier to Amazon. We are currently in testing mode with them for EDI. We are using AS2, EDIFACT standard, like required from Amazon. regarding INVOIC messages, Amazon is insisting on a specific payer address in NAD IV segment - the company name of Amazon Germany, which is about 41 characters. We have exact payer address stored in SAP, but once we make EDI transfer, the payer name segment is cut to 35 character.
What we can transmit:
NAD+IV+5450534005838::9++AMAZON EU SARL:NIEDERLASSUNG DEUTSC+Marcel-Breuer-Str. 12+MUENCHEN++80807+DE'
What AMAZON expects:
NAD+IV+5450534005838::9++AMAZON EU SARL:NIEDERLASSUNG DEUTSCHLAND+MARCEL-BREUER-STR. 12+MUENCHEN++80807+DE
Amazon is consequently rejecting our invoices after transmission as long as there is no exact match.It is insane, as Amazon itself provides documentation where the field limit is stated.
However we do not get qualified response over their vendor central. (Everyone working with Amazon knows what I mean)
Has anybody experience with EDI setup with Amazon, their requirements and this specific field limitation?
We have tried to use an abbreviation of company name, but this is not accepted. Billing address cannot be changed.
Change of field length in code not possible at the moment

Answer 1

the NAD segment has several name and address fields in composite C080 (5 of them in release D96A in fact). You can store the required name in those fields, not just in the first one. The colon in your message example is not part of the name, it is a separator for fields in a composite. It's part of the EDIFACT syntax. The plus sign separates fields and composites, the colon separates fields within a composite.
dissecting the expected NAD segment it looks like this:
NAD (Segment name)
IV Field 3035, Party Qualifier
5450534005838 Composite C082, Field 3039, Party Identification
Composite C058 is left empty
AMAZON EU SARL Composite C080, Field 3036 (first occurrence), Party Name
NIEDERLASSUNG DEUTSCHLAND Composite C080, Field 3036 (second occurrence), Party Name
MARCEL-BREUER-STR. 12 Composite C059, Field 3024 Street
MUENCHEN Field 3164, City Name
Field 3229 is left empty
80807 Field 3251, Postcode
DE Field 3207, Country coded
I personally use the EDIFACT directories from Truugo to check the message definitions:
