[Deprecated]: V4.0
/ec-datahub-svc/rest/v4.0/tenant/{tenantId}/studies/{studyId}/{mode}/subjects/forms
Deprecated: Use latest version instead.
Retrieves the study-permissioned Subject Forms dataset for a single study and mode.
The dataset exposes versioned subject form status history, including form repetition and rollover settings, entered-versus-total item counts, visit context, and audit columns.
Supports select, filter, sort, limit, and offset query patterns.
The dataset returns subject-form rows for form instances captured across visits in the selected study and mode.
This version additionally includes the following data points: IS_MISSING_FORM.
Required permission: SubjectFormDatasetPost.
Recommended order columns: The backend query always orders results by DH_TIMESTAMP and VERSION_START in ascending order first. If orderColumns is empty, only these two columns are used. If orderColumns is provided, the specified columns are appended after DH_TIMESTAMP and VERSION_START. For stable, deterministic pagination, use STUDY_ID, SUBJECT_ID, EVENT_ID, EVENT_INSTANCE_NUM, FORM_ID, INNER_REPEAT, and OUTER_REPEAT in the orderColumns field of the request payload.
