Scaling of Negative Tracing Factors 
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:
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:
No scaling (1)
Negative tracing factors are allowed for.
Standard scaling (2)
The scaling depends on the total of the receiver tracing factors:
Absolute value (negative value becomes positive) (3)
For negative tracing factors, the +/- sign is reversed. This ensures that all the receiver tracing factors are positive.
Negative tracing factors become zero (4)
Negative tracing factors are set to zero. Therefore, you do not allocate costs to these receivers.
Smallest negative tracing factor becomes zero (5)
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 0, are given a positive tracing factor.
Smallest negative tracing factor becomes zero, but zero remains zero (6)
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 0, are given tracing factor 0.

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