| 1 | RELREC | STUDYID | Study Identifier | Char | Identifier | Req | Unique identifier for a study. | |
| 2 | RELREC | RDOMAIN | Related Domain Abbreviation | Char | C66734 | Identifier | Req | Abbreviation for the domain of the parent record(s). |
| 3 | RELREC | USUBJID | Unique Subject Identifier | Char | Identifier | Exp | Identifier used to uniquely identify a subject across all studies for all applications or submissions involving the product. | |
| 4 | RELREC | IDVAR | Identifying Variable | Char | Identifier | Req | Name of the identifying variable in the general-observation-class dataset that identifies the related record(s). Examples include --SEQ and --GRPID. | |
| 5 | RELREC | IDVARVAL | Identifying Variable Value | Char | Identifier | Exp | Value of identifying variable described in IDVAR. If --SEQ is the variable being used to describe this record, then the value of --SEQ would be entered here. | |
| 6 | RELREC | RELTYPE | Relationship Type | Char | C78737 | Record Qualifier | Exp | Identifies the hierarchical level of the records in the relationship. Values should be either ONE or MANY.
