We took your file and added segments before the HL*2*1*22*0~ such as the ISA, GS, ST, the submitter and billing provider.
We also added ~ at the end of the segments provided in your file.
Attached is a qat3d.cfg map file that will work with the structure of the file your customer provided you.
Here is the command line we used to run our tests.
Note that the ML option is being used in the option string.
