I have the following example EDIFACT with two messages within an interchange.

UNA:+.? 'UNB+IATB:1+6XPPC+LHPPC+940101:0950+1'UNH+1+PAORES:93:1:IA'MSG+1:45'IFT+3+XYZCOMPANY AVAILABILITY'ERC+A7V:1:AMD'IFT+3+NO MORE FLIGHTS' ODI'TVL+240493:1000::1220+FRA+JFK+DL+400+C'PDI++C:3+Y::3+F::1'APD+74C:0:::6++++++6X'TVL+240493:1740::2030+JFK+MIA+DL+081+C'PDI++C:4'APD+EM2:0:1630::6+++++++DA' UNT+13+1'UNH+2+PAORES:93:1:IA'MSG+1:45'IFT+3+XYZCOMPANY AVAILABILITY'ERC+A7V:1:AMD'IFT+3+NO MORE FLIGHTS'ODI'TVL+240493:1000::1220+FRA+JFK+DL+400+C' PDI++C:3+Y::3+F::1'APD+74C:0:::6++++++6X'TVL+240493:1740::2030+JFK+MIA+DL+081+C'PDI++C:4'APD+EM2:0:1630::6+++++++DA'UNT+13+2'UNZ+1+1

I understand that an interchange denoted by UNB..UNZ service segments can hold multiple messages. As an example I have included two messages here as you can see.

Before I design the rules for my parser, is this message a valid message to start with? I have tried a free EDI viewer from Sourceforge, but it seems to warn it's not valid so I don't know how accurate the tool is. There are no other free EDI validator tools that I know of that I can use to check the accuracy of EDIFACT messages that I am generating using my own API I have developed in C#.

A small point, but if you had replaced the segment delimiter (') with ' Line Feeds in any text editor these type of count mismatches would have been much easier to see at first glance.

I have figured it out. I made a mistake in forgetting to set the UNZ control count to 2 to reflect there are 2 messages in the interchange.

The correct message is:

UNA:+.? 'UNB+IATB:1+6XPPC+LHPPC+940101:0950+1'UNH+1+PAORES:93:1:IA'MSG+1:45'IFT+3+XYZCOMPANY AVAILABILITY'ERC+A7V:1:AMD'IFT+3+NO MORE FLIGHTS' ODI'TVL+240493:1000::1220+FRA+JFK+DL+400+C'PDI++C:3+Y::3+F::1'APD+74C:0:::6++++++6X'TVL+240493:1740::2030+JFK+MIA+DL+081+C'PDI++C:4'APD+EM2:0:1630::6+++++++DA' UNT+13+1'UNH+2+PAORES:93:1:IA'MSG+1:45'IFT+3+XYZCOMPANY AVAILABILITY'ERC+A7V:1:AMD'IFT+3+NO MORE FLIGHTS'ODI'TVL+240493:1000::1220+FRA+JFK+DL+400+C' PDI++C:3+Y::3+F::1'APD+74C:0:::6++++++6X'TVL+240493:1740::2030+JFK+MIA+DL+081+C'PDI++C:4'APD+EM2:0:1630::6+++++++DA'UNT+13+2'UNZ+2+1

This now validates using EDIFACT Viewer.
