Question:
Why does the following error occur when a Site enters a subject identification on Data Entry in CDMS for a subject.
Answer:
If this error message occurs, it is because the Subject Identifier is already used on a different site within the same study. Subject Identifiers are unique and the format is defined during study design.
Site users need to reach out to their CRA o Data Manager to determine the appropriate approach to the case.
