Identifies the sequence number in SDTM domain XX that is the source for this row. This variable would be copied unchanged from the SDTM domain XX. Required for traceability back to SDTM when rows in the dataset are created from a single SDTM domain. This may be missing for derived rows.
For SubClass ADVERSE EVENT, use AESEQ, copied from SDTM AE.AESEQ.
SRCDOM
Source Data
Char
Perm
Not used
Identifies the name of the domain or dataset that is the source for this row. If the source data is a supplemental qualifier in SDTM, this variable will contain the value of RDOMAIN in SUPP-- or SUPPQUAL. Used when rows in the OCCDS dataset are from multiple SDTM domains or from one or more ADaM datasets. Not to be used in conjunction with --SEQ. This may be missing for derived rows.
For SubClass ADVERSE EVENT, AESEQ is used rather than SRCDOM and SRCSEQ.
SRCSEQ
Source Sequence Number
Num
Perm
Not used
Identifies the sequence number that is the source for this row. If SRCDOM is a SUPPQUAL, then this variable will contain the sequence number of the relevant related domain record. Used when rows in the OCCDS dataset are from multiple SDTM domains or from one or more ADaM datasets. Not to be used in conjunction with --SEQ. This may be missing for derived rows.
For SubClass ADVERSE EVENT, AESEQ is used rather than SRCDOM and SRCSEQ.
ASEQ
Analysis Sequence Number
Num
Perm
Perm
Sequence number given to ensure uniqueness of subject records within an ADaM dataset.
ASEQ is useful for traceability when the OCCDS dataset is used as input to another ADaM dataset and the --SEQ variable is not included or unique. ASEQ is described in more detail in ADaMIG v1.2, Section 3.3.1, Identifier Variables for BDS Datasets.
