At least 1 treatment product variable is required in a BDS dataset. This requirement is satisfied by any of the subject-level treatment product variables (e.g., TRTxxP) or record- level treatment product variables (e.g., TRTP). All treatment product variables defined in ADaMIG Table 3.3.2.1 are record level, meaning that the values contained in the variable may vary by record within a subject. Subject-level treatment product variables are described in ADD LINK Table 3.Section 2.4.

TRTP is a record-level identifier that represents the planned product attributed to a record for analysis purposes. TRTP indicates how product varies by record within a subject and enables analysis of crossover and other designs. Though there is no requirement that TRTP will correspond to the TRTxxP as defined by the record's value of APERIOD, if populated, TRTP must match at least one value of the character planned product variables in ADSL (e.g., TRTxxP, TRTSEQP, TRxxPGy).
As noted previously, at least one product variable is required even in non-randomized trials. This requirement is satisfied by any subject-level or record-level product variables (e.g., TRTxxP, TRTP, TRTA). Even if not used for analysis, any ADSL product variable may be included in the BDS dataset.

TRTA is a record-level identifier that represents the actual product attributed to a record for analysis purposes. TRTA indicates how product varies by record within a subject and enables analysis of crossover and other multi-period designs. Though there is no requirement that TRTA will correspond to the TRTxxA as defined by the record's value of APERIOD, TRTA must match at least one value of the character actual product variables in ADSL (e.g., TRTxxA, TRTSEQA, TRxxAGy).
As noted previously, at least one product variable is required. This requirement is satisfied by any subject-level or record-level treatment variables (e.g., TRTxxP, TRTP, TRTA). Even if not used for
analysis, any ADSL treatment variable may be included in the BDS dataset.

TRTPGy is the planned pooled product y attributed to a record for analysis purposes. "y" represents an integer [1-99, not zero-padded] corresponding to a particular pooling scheme. Useful when planned products (TRTP) are pooled together for analysis, for example when all doses of Drug A (TRTPG1=All doses of Drug A) are compared to all doses of Drug B (TRTPG1=All doses of Drug B). Each value of TRTP is pooled within at most one value of TRTPGy.

All dose variables defined in the following table below are record level. This means that the values contained in the variable may vary by record within a subject. These record-level dose variables, plus ADSL subject-level dose variables, can be used in addition to, but to—but not instead of, recordof—record-level product variables.
