Workflows can be nested, by referencing a StudyEventGroupDef that StudyEventGroupDef that references another WorkflowDef element. In this way a workflow can consist of several sub-workflowssubworkflows.
A workflow for the study as a whole will typically be described in a WorkflowDef that is referenced from the Protocol element. Workflows that are valid for a "study cell" (as described in the SDTM-IG SDTMIG) , will be described in a WorkflowDef that is referenced by a StudyEventGroupDef representing a " study cell ", (i.e. with the , ArmOID and EpochOID being are populated). Workflows that are valid for a " study element " (as described in the SDTM-IG SDTMIG) will be described in a WorkflowDef that is referenced by a StudyEventGroupDef without ArmOID and EpochOID populated, and referenced by a "parent" StudyEventGroupDef representing a " study cell ", (i.e. with the , ArmOID and EpochOID being are populated.
