I am sure it seems your EDI file formatting is not right…some thing messed up the delimiters when you copy and past while submitting to TN and its a common unrecognized errror.
Please check the file closely and format it correctly with some record delimiter (end of each segment for example a pipe | can be used) to make your sample working:
see example:
ISA~00~ ~00~ ~12~2222222222 ~ZZ~111111111 ~121112~1016~U~00401~000000219~0~P~^|
GS~IN~2222222222~111111111~20121112~1016~219~X~004010|
ST~810~0965|
BIG~20120924~9001959622~20120910~E2012090582~~~IN~00|
