Locking and unlocking parameters

When creating the workflow, the workflow author can specify which parameters should be locked or unlocked. If a parameter is locked, it cannot be changed in the installation or the execution step. Conversely, if it is left open, that parameter can be changed, either when running the Workflow or when installing it (see Distributing and installing workflows).

By default, data parameters are unlocked. When installing the workflow on a different system to the one where it was created, the connection to the data needs to be re-established. This is only possible when the parameter is unlocked. Data parameters should only be locked if they should not be set, or if the workflow will only be installed in a setting where there is access to the same data in the same location as the system where the Workflow was created.
