Periodic consumption

[Former Member]

Dear Experts,

while doing estimation, its taking periodic consumption instead of previous meter reading results.

in el28 if i chk the overview of validations,

my forecast period and the original period dates are appearing same, actually it shouldn't be same,

can any one having idea on this please help me.

thanks..

Hi,

Please check the base period category you have maintained in utility installation screen (Tcode ES32).

If it is maintained as 'Previous period' then the previous period is used as a basis for extrapolation. If it is 'Period of previous year' then period of the previous year is used as a basis for extrapolation.

Now if there is a change in the periodic consumption value in the reference period which will be used for extrapolation, SAP will not look at the meter reading value. SAP will directly use the periodic consumption value for estimation of the current period. The periodic consumption value is available in table EASTE and you can see it from transaction EL56.

Hope it will help.

Thanks.

Hi Nirmalya,

Thanks for reply, but from config side everything is ok, like in installation base period was maintained as previous period.

and comming to period consumption (PC) , there it was maintained 4 time slices like:

14.11.2008 : 27 (PC) : 365 (number of days)

2.3.2009 : 5 (PC) : (30)

2.3.2011 : 113 (pc) : (365)

16.5.2011 : 113 (pc) : (365)

if i delete the last two time slices (2.3.2011 and 16.5.2011) its working fine,

can u help me on this..

thnanks..

Hi Nirmalya,

Concerning  periodic consumption, how the estimate is calculated? Can you please give an example.

Secondly concerning the weigthing key 5 and units define as below:

05 | 01.01 | 150

05 |01.02  |120

05 |01.03  |100

05 |01.04  |90

05 |01.05  |60

What the use of these values ? How the calculation is done before giving an estimate?

To be more precise, the min portion is define as 600% and period length is 20 means 120 days. But there are cases where the estimate is done well beyond 120 days.

Also for the 120 days, will it count only working days in factory calender or all days(working/non working/saturday/sunday/public holidays)?

Your help will be highly appreciated

Regards,

Gavisht

Hi,

Please see the explanation below:

The main factor of extrapolation depends on the base period category option which is selected in the utility installation section. There are two options which are Previous period and period of previous year.

There is another factor which controls the extrapolation is the minimum portion in percent maintained at the register rate level.

For example,

if you have selected the base period category as 'period of previous year'

minimum portion in percent is selected as 80%

your period length in portion is 365 days,

Start of extrapolation day is 16-May-2011

SAP will start looking from 16-May-2010 and will try to get the meter reading for (365 * 0.8) = 292 days for extrapolation. SAP will now go 292 days in past from 16.05.2010 and will get the meter reading. If there is no meter reading on exact 292 days in past, SAP will take the earlier reading of that date. Also if there is no reading on 16.05.2010, SAP will internally calculate the reading by using the last and next meter read of 16.05.2010 using unitary method. After calculating the reading of 16.05.2010 and getting the reading of 292 days in past from 16.05.2010, SAP will calculate the per day consumption for that period using unitary method (which is total consumption/number of days). That will be used for extrapolating the current consumption. If you are currently extrapolating for 35 days, the per day consumption will be multiplied by 35 to get the consumption for the current period.

If ther is not enough meter reading 292 days in past from 16.05.2010, SAP will use the periodic consumption maintained at register level for extrapolation.

If you specify a small minimum percentage in register rate, meter readings from a short period will be used for the extrapolation.

If you enter 100% for the minimum percentage in the register rate, available readings will only be used if they cover a complete billing period.

Now if your base period category is maintained as 'Previous period' in installation, SAP will start looking a meter reading from 15.05.2011 to 292 days in past from 15.05.2011. SAP will calculate internally the meter readings for the date which is 292 days in past and will calculate the per day consumption of that period for extrapolation of the current period starting from 16.05.2011.

If there is not enough meter reading for 292 days in past, SAP will use the periodic consumption value maintained at register level.

Please note that updating the periodic consumption at register level directly impact your meter reading extrapolation process. If there is a change in periodic consumtion in the base period, SAP will use the periodic consumption value straightaway for current period extrapolation. It will not calculate the per day consumption in the same way as I have mentioned as above.

Hope it helps.

Thanks.

Hi Nirmalya

Thank you very much for your valuable explanation reply,

its very helpfull.

cheers.
