General Issue: derive_var_studyeye() accidentally uses hardcoded subject keys

[manciniedoardo]

Background Information

  derive_vars_merged(
    dataset_adsl,
    dataset_add = dataset_sc,
    by_vars = exprs(STUDYID, USUBJID), 
    order = NULL,
    filter_add = SCTESTCD == !!sctestcd_value,
    new_vars = exprs(STUDYEYE = SCSTRESC),
    mode = NULL,
    missing_values = exprs(STUDYEYE = "")
  ) 

Should be:

  derive_vars_merged(
    dataset_adsl,
    dataset_add = dataset_sc,
    by_vars = get_admiral_option("subject_keys"),
    order = NULL,
    filter_add = SCTESTCD == !!sctestcd_value,
    new_vars = exprs(STUDYEYE = SCSTRESC),
    mode = NULL,
    missing_values = exprs(STUDYEYE = "")
  ) 

Definition of Done

Replace problematic line!
