STUDYID | Study Identifier | Char |
| Req | DM.STUDYID, ADSL STUDYID, and/or STUDYID from another ADaM or SDTM dataset appropriate to the analysis. | USUBJID | Unique Subject Identifier | Char |
| Req | DM.USUBJID, ADSL.USUBJID, and/or USUBJID from another ADaM or SDTM dataset appropriate to the analysis. | SUBJID | Subject Identifier for the Study | Char |
| Perm | DM.SUBJID, ADSL.SUBJID, and/or SUBJID from another ADaM dataset appropriate to the analysis. SUBJID is required in ADSL, but permissible in other datasets. | SITEID | Study Site Identifier | Char |
| Perm | DM.SITEID, ADSL.SITEID, and/or SITEID from another ADaM dataset appropriate to the analysis. SITEID is required in ADSL, but permissible in other datasets. | ASEQ | Analysis Sequence Number | Num |
| Perm | Sequence number given to ensure uniqueness of subject records within an ADaM dataset. As long as values are unique within a subject within the dataset, any valid number can be used for ASEQ. ASEQ uniquely indexes records within a subject within an ADaM dataset. ASEQ is useful for traceability when the dataset is used as input to another ADaM dataset. To refer to a record in a predecessor ADaM dataset, set SRCDOM to the name of the predecessor dataset, and set SRCSEQ to the value of ASEQ in the predecessor dataset. |
