Hi Sean,
please add
OUTPUTHEADER=
OUTPUTDELIMITER=
to your transformation file, think also to start from default export file
*OPTIONS
FORMAT=DELIMITED
HEADER=YES
DELIMITER=
VALIDATERECORDS=NO
ROUNDAMOUNT=7
OUTPUTHEADER=
OUTPUTDELIMITER=
*MAPPING
*CONVERSION
this should work, after add instructions one by one and see if works, same with conversion files, probably the issue is in your conversion files maybe a value in the fact tables not included in conversion.
Regards
Roberto
