APAR status

• Closed as program error.

Error description

• Problem Description: When using Sliding-Days Average as
  Calculation Method, the Average Units/Day is calculated
  incorrectly.
  
  STEPS TO REPRODUCE:
  
  1. Go to Assets application.
  
  2. Create a new Asset record with any valid number, save and
  change its Status to OPERATING.
  
  3. Go to Meters tab, click on New Row button, enter the
  following and save the record:
  
  Meter: ODOM-M
  Average Calculation Method: SLIDING-DAYS
  Sliding Window Size: 14
  Reading Type: ACTUAL
  Rollover: 999,999.00
  Last Reading: 100
  Last Reading Date: 11/1/18 ***
  
  *** Note:
  In this example, as the system date is 11/15/18 and the Sliding
  Window Size is 14, enter Last Reading Date as 11/1/18, which is
  11/15/18 - 14.
  
  4. From More Actions menu, select Enter Meter Readings.
  
  5. Enter the following Meter Readings and save the record:
  
  New Reading ..... New Reading Date
  200 .................... 11/2/18
  300 .................... 11/3/18
  500 .................... 11/5/18
  
  6. Now Enter the following Meter Reading and save the record:
  
  New Reading ..... New Reading Date
  400 .................... 11/4/18
  
  RESULTS:
  System calculates Average Units/Day as 131.51 incorrectly. This
  is the issue.
  
  EXPECTED RESULTS:
  Average Units/Day should be 100.

  ****************************************************************
  Average Units/Day is recalculated incorrectly. New readings that
  aren't most recent readings should not impact the average if
  there is an already-existing more recent reading that is an
  ACTUAL reading. ACTUAL readings stop the updating of the more
  recent readings that results from the entry of a new but older
  reading date. As a result of the updates stopping once an ACTUAL
  is encountered, the current, most recent reading remains
  unchanged. Given that the current reading is unchanged, the
  average should also be unchanged.
  
  STEPS TO REPRODUCE:
  1. Go to Assets application.
  
  2. Create a new Asset record with any valid number, save and
  change its Status to OPERATING.
