About SVP Algorithms

The following two algorithms are available in the SVP module:

• Percentage Change. Modifies the source value by a percentage and populates the target proportionately. A period definition is not required.
• Trended Volume Period. Compares the value in the Trended Volume Period to the value in the Source Period to obtain a variance, and uses this variance to extrapolate the value in the target period. A period definition is required. Table 11 shows an example of trended volume period calculations.

  Table 11. Trended Volume Period Calculations

  Source Period	Trended Volume Period	Variance	Target Period
  Start: Week 1, 1998 (Quantity:100)	Start: Week 1, 1999 (Quantity: 110)	10% increase (from source period to trended volume period)	Start: Week 1, 2000 (Quantity: 121) Apply Variance to the value in the trended volume period to obtain the value in the target period.
  End: Week 2, 1998 (Quantity:100)	End: Week 2, 1999 (Quantity: 90)	10% decrease (from source period to trended volume period)	End: Week 2, 2000 (Quantity: 81) Apply Variance to the value in the trended volume period to obtain the value in the target period.
