Problem conclusion

• THIS PROBLEM WILL BE FIXED ON   VERSION V5R20 GA level.
  NOTE
  THAT THIS PROBLEM WILL ALSO BE FIXED ON V5R19 SP6.
  Additional
  Closure Information:
  Incident Diagnosis:
  The value of area is
  different on "Measure" result and "Formula"
  result.
  .
  Correction Explanation:
  The problem is seen because
  the methods used for computing the Area is different using
  MEASURE and using Formula. Thus resulting in a difference in
  the results.
  Now, a common approach is used in MEASURE &
  FORMULA such that the results are same.
