SDTMIG 3.3 (FDA).
In my RE datasets, I have measurements for which the same device was used. So, I have more than one measurement per unique device.
Although my values of RESEQ are unique for each measurement within each subject, I get a large numbers of errors SD005 "Duplicate value for RESEQ variable".
row 1: USUBJID=21, SPDEVID=DEV33, RESEQ=1
row 2: USUBJID=21, SPDEVID=DEV33, RESEQ=2
It looks as the software wants to have SPDEVID being unique within each subject, which has nothing to do with RESEQ.
SDTM-IG shows a lot of examples where SPDEVID is not unique within each subject, e.g. page 227.
