The document discusses the Dynamic Modification Factor (DMF) used in SAP to prevent large jumps in synthetic profile values. The DMF is a predefined function that calculates a factor multiplied against synthetic profile values. It can be used with day or annual profile allocations and cannot be regenerated once used. Custom DMF algorithms can also be defined. The standard VDEW DMF algorithm calculates a factor based on the date that is multiplied against profile values to generate final synthetic profile values.

1. Dynamic Modification Factor
Used in Synthetic Profiles to change the values. Basic idea was to prevent large jumps in
values like in the case shown below. (Copied from help.sap.com)
SAP has a predefined dynamic modification function for residential customers which comply
with the standards of the German Electricity Association. The Function Module is
ISU_FACTOR_PROFILE_CALC_0001.
• DMF profiles should be of profile type ‘elementary’ and of profile value category ‘factor’.
• DMF is only valid for Synthetic Profiles which have ether the day profile allocation or
annual profile allocation.
• Once the DMF values are generated and used in a Synthetic Profile they cannot be
regenerated.
• DMF profile allocated to a Synthetic Profile cannot be changed after it’s saved.
So basically DMF is calculating a factor which is multiplied with the values which are
allocated in the synthetic profile using the day/annual profiles.
We can define our own algorithm for DMF. The customizing path to define it is in
SAP Utilities -> Tools -> System Modification -> User –Defined Enhancements for Energy Data
Management -> Dynamic Modification Functions for Synthetic Profiles -> Define Functions for
Calculating Dynamic Modification Factors

2. About the Standard VDEW Dynamic Modification Factor
t is the number of day starting with January 1 and ending with December 31 taking into
account if the year is a leap year. In real time we get the factor in prof_value. (Here for
01/01/2012 it’s calculated as 1.24203011960800) So this value gets multiplied with the
values in the Synthetic Profile for that day.
Now just a short demo on how it works.
Below is a profile with profile value category ‘factor’. The values for January month have been
stored manually as ‘2’. So this means that we have not still executed DMF algorithm but
manually assigned the multiplication factor as ‘2’.

3. The synthetic profile has season types defined so we have 2 day profiles allocated with
Summers having value as ‘10’ and Winters having value as ‘2’. The demo is showing just the
winter values.
Now for generation of values in the Synthetic Profile, we have the factor profile allocated in
DMF factors field, the dates are defined, and the status is ‘red’. So we click on the ‘generate

4. profile values’ button.
Once the profile is saved the status changes to green and the dates are updated.
The value in the winter day profile (2) as multiplied with the DMF (2) and then updated to the
Synthetic Profile as we see below. (Value of 4)
If DMF values are not maintained for a period and we try to generate the synthetic Profile it
would give an error.

5. Now generating the DMF values using the standard report.
Values are generated as shown below.
Once again the Synthetic Profile values are generated for 2012 and we get the below result.
Winter profile value(2) is multiplied with the DMF value calculated by the SAP given algorithm
as shown above.

6. So that’s it.
