Define
Characteristic Derivation
In this step, you set up the derivation of
characteristic values.
Derivation lets you find values for certain
characteristics automatically based on the known values of other
characteristics, where these characteristics are logically dependent on one
another.
Standard
Settings
When an operating concern is generated, the
system produces a standard derivation strategy containing all known
dependencies between characteristics. You can display these by choosing "View
-> Display all steps".
Activities
You can change the standard derivation strategy
by
- Creating additional steps
- Adjusting changeable standard steps to suit
your situation or deleting them
- Changing the step sequence
Proceed as follows:
Creating a step
1. Select the
step that is to precede the new step you wish to add. Choose "Create
step".
2. Choose the
desired type of derivation step from those available.
3. Enter a text
as well as source and target fields for the derivation step. By using the
arrow button, you can determine field characteristics for the
source and target fields.
4. If the
derivation step should only be executed unter certain
conditions , such as only for specific characteristic values, make
the entry under "Condition".
5. You
determine step characteristics under "Characteristics". For
example, you determine whether an error message should be generated if no
target value can be calculated.
If you use the derivation step type "Derivation
rule", some additional entry options are available:
- Under "Maintain rule values", you enter which
values in the target fields should be placed in which characteristic values of
the source fields.
- Under "Characteristics", you can make
additional entries which, for example, make it possible to enter a validity
date for the step.
Changing/deleting
steps
You can change and delete the steps you have
defined as well as the changeable standard steps (those that read from
tables).
- When you change a step, all the possible
entries described under "Creating steps" are available.
- To delete a step, select the step in question
and choose "Delete".
Changing the step
sequence
1. Select the
step to be relocated in the sequence.
2. Position the
cursor beneath the desired position for that step.
3. Choose
"Move".
