Forecast Errors

[Former Member]

Hi Experts

When i generate forecast all the Errors are also generated in the following way..

MAD 562,33.10

MAPE 10002,22.0

ET:5667,22.12

MSE 3100,229.999

RMSE 13.23

Here i am unable to find out the wat is commas and decimal in the error values.

Wat is Comma and Decimal point in the above errors.

2)When i manually check the Error total as per the formula in the SAP HELP the results are not matching.

Please give your valuable suggestion on the Forecasting errors.

regards

Sai

Hi Sai,

The way comma or decimal is used is based on your user setting. In your user profile ( through SU01 defaults tab) or in any sap window, go to System>User profile> own data> defaults tab

check the value in decimal notation.

If this value is 1,234.567,98, the decimal is used to seperate the numbers and comma is used to seperate the integral and decimal part of the number.

2) results don't match....make sure you use everything same as the sap help. Also as the name says "error" is always a approximate number. Unless there is a huge difference, let's say you see 10 now and 1000 next time the error within some range is always common.

Hi

First of all thanks for your Valuable Information provided.

The statement which you have used is not clear.

If this value is 1,234.567,98, the decimal is used to seperate the numbers and comma is used to seperate the integral and decimal part of the number.

In my example , System is thrown mad value as below:

MAD 562,33.10

So what is the mad value in my example whether it is 562.3310 or 56233.10 .Please explain me bit detail.

with regards

Hi,

If your user setting has "Decimal Notation" in the format 1,234.567,98

then your error as shown in APO system MAD 562,33.10

is actually 562.3310.

A value of 1 would be shown in APO as 1,000

A value of 1.2 would be shown in APO as 1,2
