When an ARM variable does not exist but TRT0xA or TRT0xP variables do exist, distribution reports produce the following error:
could not find column in access or evaluation of 'Column' , Column/*###*/("Trt")
Selecting TRT01A or TRT01P as the treatment variable to use also produces the error. If you add ARM to the data set or select ARM as the comparator to use, no error occurs.
This error is commonly seen in crossover studies where multiple treatment variables exist.
It is resolved in the JMP® Clinical 7.0.1 hotfix (link below).
