Variables used for datapoint traceability may also include any other variables that facilitate transparency and clarity of derivations and analysis.

SRCDOM

Source Data

Char


Perm

The SDTM domain name or ADaM dataset name that relates to the analysis value (i.e., AVAL or AVALC in a BDS dataset). If the source data is a supplemental qualifier in SDTM, this variable will contain the

value of RDOMAIN in SUPP-- or SUPPQUAL.

SRCVAR

Source Variable

Char


Perm

The name of the column (in the domain or dataset identified by SRCDOM) that relates to the analysis value (i.e., AVAL or AVALC in a BDS dataset). In the event that SRCDOM is a SUPPQUAL, then SRCVAR will be populated with the value of the related QNAM.

SRCSEQ

Source Sequence Number

Num


Perm

The sequence number --SEQ or ASEQ of the row (in the domain or dataset identified by SRCDOM) that relates to the analysis value (i.e., AVAL or AVALC in a BDS dataset). In the event that SRCDOM is a

SUPPQUAL, then this variable will contain the sequence number of the relevant related domain record.


If the value of AVAL or AVALC in the ADaM dataset is taken from another ADaM dataset, SRCDOM, SRCVAR, and SRCSEQ will contain the name of the source ADaM dataset, the variable name, and the ASEQ value of the row where the source datapoint is located, respectively. If the source SDTM dataset is a supplemental qualifier dataset, the two-letter domain prefix of --SEQ in the ADaM dataset will be the related domain abbreviation (the value of RDOMAIN in SUPP-- or SUPPQUAL), and SRCVAR will contain the value of QNAM.
