ORA-10632 - Invalid rowid

Question

Hi All,
I have scheduled a job to execute the following code to perform row movement and shrink space weekly. However, I encounter ORA-10632 while running this job. I have read the online solution to resolve this issues is to re-issue the command.
Is it because there are too many tables executing enable row movement and shrink space which causes ORA-10632 error?
Please advise.
Thank you.
BEGIN
      OPEN cur FOR
         SELECT TABLE_NAME
          FROM TABLE_MAINTENANCE;
      LOOP
        FETCH cur
            INTO p_tablename;
        EXIT WHEN cur%NOTFOUND;
        EXECUTE IMMEDIATE 'ALTER TABLE ' || p_tablename || ' ENABLE ROW MOVEMENT';
        EXECUTE IMMEDIATE 'ALTER TABLE ' || p_tablename || ' SHRINK SPACE';
      END LOOP;

Hello,
Cause :      Segment Highwatermark was overwritten due to shrink and space reused
Action :      Reissue this command.
Therefore, perhaps:
BEGIN
     EXECUTE IMMEDIATE 'ALTER TABLE ' || p_tablename || ' ENABLE ROW MOVEMENT';
        EXECUTE IMMEDIATE 'ALTER TABLE ' || p_tablename || ' SHRINK SPACE';
  EXCEPTION
    WHEN OTHERS THEN
       EXECUTE IMMEDIATE 'ALTER TABLE ' || p_tablename || ' SHRINK SPACE';
END;
