The type of generation technique that you can apply depends on the datatype of the column that you need to generate. When you choose a generation technique, Test Data Manager displays parameters for the generation technique.
Some generation techniques are available only for ad hoc generation rules. The generation techniques that you can select to create a rule can change when you create an ad hoc generation rule.
You can create generation rules that create random strings, use data from a dictionary or set of values, or that create data based on a sequence that you define.
