Decisions – simple logic in a visual designer
Let's have a brief look here at the decision you created for a dynamic assignment:
Figure 14.1 – Dynamic assignment decision
Here, we take the amount as input, and depending on a threshold we return one group or another. In general, a Decision object in Appian applies some logic to inputs and returns matching output. The limitation here is that we cannot define any dynamic runtime behavior such as data manipulation or database queries.
But we can configure a decision to do a bit more than just simple input-to-output mapping. Our options are presented here:
- Hit Policy: Define that only a unique single row can match the first or multiple rows (Rule Order)
- Logical Operator: Define in which way the input value should be compared
- Multiple Inputs: Create one or more inputs to implement multiple condition logic
- Multiple Outputs: Create one or more outputs to return groups of values...
