Question

after that i need to check meter reading is too high, too low, correct.
and date of meter reading is early, late, correct.
is their any standard FM which i can use?
or do we have maximum, minimum values predefined for meter reading in any table?
i have checked table TE121 but no use.
please guide me

Hi,
Hi,
The way the others have suggested is correct. you can use the tolerance in config validation.
you can enter consumption range against validation class with positive & negative deviation.
example
RESI               1 to 100                +deviation 300                   -ve deviation 30
this validation works on base period category
If the base period is previous period, then it will take the consumption of previous month (else previous period last year)
Now the total number of days for previous month are 30 and unit consumed is 900
now we will calculate the number of days to be assessed & multiple it with per day consumption, this will yield expected consumption. for ex. no of assessed days are
28 then 28 *30 = 840 units
from expected consumption you can calculate the min/max consumption depending what you have defined in tolerance
like here 300%  positive deviation means total 400% means 840 *4 = 3360 unit max consumption
& 30% negative deviation means total 70% (100-30) means 840*.7 = 588 unit min consumption
Means in this range the consumption will not be implausible (from 588 to 3360), otherwise system will automatically make the reading implausible.
so the
Expected MR                   last reading +840
Upper limit of MR             last reading +3360
Lower limit of MR            last reading +588
I hope, it will help in solving your issue.
