    //  out field selection lists. The three other member lists of a TSItem:
    //  changeList, attachmentList and linkList, will not be updated. The
    //  bLockFlag is defaulted to lock this record. While the record is
    //  locked, any other user (via API or browser interface) will receive
    //  an error (TS_LOCK_UNAVAILABLE for API) if they attempt to update
    //  the same record. The time a lock is held is set by the TeamTrack
    //  administrator. The table id and item id must be preset.
