Hi
Can some one please help me to understand this error

 pumdf = read_pumas(phen1, observations = [:DV], id = :ID, time = :TIME, amt = :AMT, rate = :RATE, cmt = :CMT)

In Pumas NLME Data (PumasNDF), each id can have only unique time points. It seems that your subject 45 has two time points that are similar. It is likely the subject was two observation records that have the same time. This is not allowed in Pumas, so please check your data.
