You can link all important arguments for tasks used across the build definition as process parameters, which are then shown at one place - the Pipeline view. This means you can quickly edit these arguments without needing to click through all the tasks.
Templates come with a set of predefined process parameters.
The Link and Unlink functionality applies to build pipelines only. It does not apply to release pipelines.
To link additional arguments across all tasks to new or existing process parameters, select Link from the task argument.
You can link additional arguments across all tasks to new or existing process parameters.
Select Unlink if you need to disconnect an argument from a process parameter.
You can also unlink arguments from process parameters.
Process parameters differ from variables in the kind of input supported by them. Variables only take in string inputs while process parameters in addition to string inputs support additional data types like check boxes and drop-down list boxes.
