Scaling of Negative Tracing Factors 

Use

Negative tracing factors can occur if the tracing factors are given not as quantities or percentage rates, but are taken from the database. This is the case, for example, with a distribution by activity types or statistical key figures.

The scaling of negative tracing factors is only of importance when the receiver tracing factors have different +/- signs.

If part of the receiver has positive and part negative tracing factors, we distinguish between two cases:

·        If the total of all the receiver tracing factors is greater than zero, then the system credits (without scaling) the receiver as well as the sender with negative tracing factors. In the process, receivers with positive tracing factors are debited more heavily.

·        If the total of all the receiver tracing factors is less than zero, the system credits (without scaling) the receiver as well as the sender with positive tracing factors. The receivers with negative tracing factors are thus debited more heavily.

In iterative processing, this can mean that the iteration does not converge, leading to cancellations or incorrect results.

Features

You have the following options for scaling negative tracing factors (numbering refers to table below):

       1.      No scaling

Calculations use negative tracing factors.

       2.      Standard scaling

The scaling depends on the total of the receiver tracing factors:

¡        If the total of the receiver tracing factors is positive or zero, then the largest negative tracing factor is set to zero. The other tracing factors are increased correspondingly. This ensures that all the receiver tracing factors are positive.

¡        If the total of the receiver tracing factors is negative, the largest positive tracing factor is set to zero. The other tracing factors are reduced correspondingly. This ensures that all the receiver tracing factors are negative.

       3.      Absolute value (negative value becomes positive)

For negative tracing factors, the +/- sign is reversed. This ensures that all the receiver tracing factors are positive.

       4.      Negative tracing factors become zero

Negative tracing factors are set to zero. Therefore, you do not allocate costs to these receivers.

       5.      Smallest negative tracing factor becomes zero

The largest negative tracing factor is set to zero. All other tracing factors are increased correspondingly. This ensures that all the receiver tracing factors are positive. Receivers, which before the scaling had the tracing factor zero, are given a positive tracing factor.

       6.      Smallest negative tracing factor becomes zero, but zero remains zero

The largest negative tracing factor is set to zero. All other tracing factors are increased correspondingly. Receivers, which before the scaling had the tracing factor zero, are given tracing factor zero.

Example of Scaling Negative Tracing Factors

	1	2	3	4	5	6
Tra. fac. rec. 1	-100	0	100	0	0	0
Tra. fac. rec. 2	200	300	200	200	300	300
Tra. fac. rec. 3	-50	50	50	0	50	50
Tra. fac. rec. 4	0	100	0	0	100	0
Total tra. factors	+ 50

The scaling of negative tracing factors can be set only for individual allocation segments and not for the entire cycle.
