How the Upper limit and Lower limit of MR order are determined

[Former Member]

Hi Experts,

For our client,the  % Positive deviation of the independent validations are maintained relatively high.So even if the meter reading is very high, the system is accepting the reading as plausible meter reading and while billing they got to know that the meter reading is very high and stopped billing of these accounts.

Now I am analyzing this issue and I have few queries .

1.When  creating the MR order either by EL01/EL09,the upper limit and lower limit of MR is determined.Based on which parameters these are determined.

(I know based on periodic consumption of base period.But are there any parameters else comes to picture )

2.Are the lower and upper limits of the MR order calculated same as estimated meter read.

3.Is there any table which stores these lower and upper limits of the MR order.

4.How the percentage of portion in rate effects lower and upper limits of the MR order.

Thanks in Advance

Hi ramireddy,

You must maintain the relevant validation parameters in the Define Validation Parameters activity. You must also establish settings in the Define Tolerance Limits activity if you choose one of the following validations:

• 05 Tolerance limits (absolute)
• 06 Tolerance limits (relative)
• 07 Tolerance limits (moving)

You can store percentages here. The percentages are multiplied by the expected consumption and then added or subtracted. The consumption values calculated form the limits of the valid interval.

Hi Ram,

The following factors are taken into consideration when deciding the Lower limit of the MR(Which I presume you might be knowing):

1) Minimum portion maintained in the Rate

2) Weighing Keys maintained for the Base Period and the Period to be estimated

3) Values maintained for the Tolerance value checks for Independent Validation

In Case of a Linear Weighing the Rule is :

Consumption in the required period = ( Consumption in the Base Period * Sum of the Weighing Keys for required period ) / ( Sum of the Weighing Keys for Base period ).

Now coming to your questions:

Lower Limit is the same calculation as that for the Estimated Readings

Min and Max value are alqays calculated in the runtime and then stored in EABL.

Percentage of Portions helps define the Base Period for calculation of the Base consumption.

For further details on how it actually calculates the Min and Max look at the FM ISU_DETERMINE_TOLERANCE_LIMITS

Hope this helps...

Hi Sitakant,

Thanks for all your clarifications.

But I still had some questions left.

Are the estimated value and the lower limit ,the upper limit of MR are calculated in the same manner.

Where in the calculation of Upper,lower limit of MR ,the tolerance limits maintained in the config will have impact i.e. As said by Sai in the above answer,are the percentages mailtained in the tolerance limits just get multiplied to the estimated value when determining the lower limit and the upper limit of the MR.

We are using Degree day weighing,how it effects the determination of lower limit and upper limit of MR.

Thanks in Advance

Hi sundar,

1. Tolerance Limit's are used in validation.

In Customizing sap utilities --> DM--> MR --> Validations --> Independent Validations --> Define Tolerance limits for Validation classes

Hi,

There are 2 types of Validations.

1. Independent Validations.

2. Dependent Validations

Independent Validations

•Validation that applies to one specific register.

•Fixed independent validations are carried out automatically in the system.

•Variable independent validations are carried out based on customizing settings.

Fixed Independent Validations are

•95 (previous meter reading implausible)

•96 (fixed value deviation validation)

•97 (resetting register validation)

You must maintain the relevant validation parameters in the Define Validation Parameters activity

• 05 Tolerance limits (absolute)
• 06 Tolerance limits (relative)
• 07 Tolerance limits (moving)

Example:

Periodic consumption : 300 for 30 days.

Validation class 0001: 05 Tolerance limits (absolute)

Parameters :error/warning.

Tolerance limits: For consumption 0 to 399

1. 1. Warning displayed

+dev 20 units and –dev 20 units

1. 2. Error displayed

+dev 30 units and -30 units

For Consumption 400 to 999

1. 1. Warning displayed

+dev 20 units and –dev 20 units

1. 2. Error displayed

+dev 30 units and -30 units

Now You check the MR entry.

I think this will help you.
