  • 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 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. ©
