Hi PK,
P21 Validator has
- SD1152 (Duplicate records per Key Variables in Define.xml)
- and several other rules for duplicate records per pre-specified Keys Vars. SD1117 for Findings domains, SD1201 for Events, SD1352 for Interventions, SD0086 for SUPPQUALs, etc.
Those two types of rules serve different purposes.
Kind Regards,
Sergiy
