Scalar Estimations Are Resulting In 'Regular' Reads Being Tagged As Do Not Use. (Doc ID 2099990.1)

Oracle Utilities Meter Data Management - Version 2.1.0.3 and later
Information in this document applies to any platform.

Symptoms

In Meter Data Management 2.1 SP3 (2.1.0.3) for Consumption synchronization between Scalar and Interval channel, there is a case when System-Generated Manual IMD (Data Source: Generated by Reconciliation) throws error as: “Unable to complete Manual IMD: The IMD contains measurements whose condition value is of lesser quality than the existing measurements for the same measurement date and time.” This error is due to the fact that system creates re-conciliation Manual IMD by inputting Condition Code from next measurement; instead it should be taken from final-condition. If above exception is suppressed by making VEE Exception severity to Information, there are following case when regular measurement will be marked as Do-Not-Use. In this case, when Initiating IMD is estimated higher such a way that it’s end read is greater than next regular measurement, system currently marking next regular measurement to Do-Not-Use.

Steps to Recreate

I. Setup

  1. Create Device, Device Configuration and two Measuring Components (1 interval [SPI = 1 Hour] and 1 AMR scalar MC);
  2. Create a VEE group with the Scalar Calculation from Interval VEE rule added to it as follows:
    1. Section: Scalar Calculation From Interval
      1. Minimum Condition to Preserve Measurement = Regular
      2. IMD Created Condition Value = Office Estimate
    2. Section: Override Condition for High Quality Source Measurements
      1. Minimum Condition Quality to Override = Regular
      2. Override Condition Value= Regular
  3. In the scalar MC, make the interval MC created as the Consumption Reference Measuring Component (Interval MC as Primary MC).
  4. Create the Service Point and the Installation Event.

II. Existing Usage Data

  1. AMR Scalar MC has “regular” measurements as shown below:
    1. Date End Read Condition
      01-Oct 0 Regular
      06-Oct 60 Regular
      07-Oct 70 Regular
  2. Related Interval MC has complete measurements for above periods such that it has high consumption (say 720) between 01-Oct to 04-Oct.
  3. AMR Scalar MC has “Scalar Calculation from Interval” estimation-VEE rule.

III. Steps to Reproduce Behavior

  1. Submit a Manual IMD on 4 Oct, with System Estimate condition so that it can be estimated by VEE rule.
  2. Notice that 04-Oct IMD marked both measurement on 06-Oct and 07-Oct to Do-Not-Use since it is estimated high (end-read = 720) by VEE rule
