I wanted to ask what is the source of rule AD0245 "CNSR is present but STARTDT" and similar rules 246-249? For example, for 245, in ADaM BDS for TTE specification STARTDT is marked as permissible. Other variables mentioned in 246-249 are also permissible. I could not find this rule in ADaM conformance rules (neither in version 1.2, nor in 2.0). Was there any clarification from the ADaM team or regulatory agencies regarding it? In ADaM conformance rules 2.0 a related rule 170 ("If STARTDT is present then CNSR must be present") is not present anymore.
