N.B.! Test Indicator
Volvo uses the Edifact test indicator in UNB 0035 for all test files to and from Volvo. Make sure to verify that you currently do no send test indicator in UNB 0035 in any production files, otherwize they will not reach the final destination. Files marked with TEST in UNB 0026 will not be handled, i.e. deleted.
Find the UNB specification under specifications/general in a document called "Application of ISO/edifact and OFTP.
