Within a flow, you can create and manage flow parameters, including specifying override values. From the flow menu, select Parameters.

You specify flow parameters at the flow level. They can be invoked in any recipe within the flow.

Tip: Override values apply to all parameters in the flow that share the same name, even if they are output object parameters.


Tip: Flow parameters can be inherited from upstream flows. For example, if you create a reference dataset that references flow parameters from its flow, those parameters are passed to the downstream flow. While you cannot change the default value for the downstream instance of the parameter, you can apply override values for all recipes in the downstream flow.

Parameters Tab

In the Parameters tab, you can manage the flow parameters in your flow.

NOTE: Non-flow parameters cannot be edited or deleted from the Parameters tab. These parameters must be modified in the interface for the object to which they apply. Overrides can be applied to these types of parameters through the Overrides tab.

When reviewing parameters for your plan, you may notice that a parameter has multiple values:

NOTE: When a parameter has conflicting values from objects in a plan task, you must fix them by applying a single override value. If these values are not fixed, then the plan fails to execute.



Parameters tab

After you create a parameter, you can insert it into your recipes using the following type of reference:

${myRecipeParameterName}

For more information, see Create Flow Parameter.

Overrides Tab

In the Overrides tab, you can apply override values to any parameters referenced in your flow, including:

NOTE: The parameters listed in this tab have override values applied to them. Parameters that are using their default values in this flow are not listed.


Overrides tab

All of the available parameter overrides are listed. 

A note on upgraded parameters

If you have upgraded from a version of the product before Release 7.1, any parameters that were defined in the previous version appear grayed out in the Parameters tab.

Manage Parameters for Plans

You can also specify parameter overrides at the plan level. For the recipes in your plan, you can pass in parameter overrides values, which are used during plan runs.

Manage Parameters Dialog for plans

In the Manage Parameters dialog, you can review the parameters that are defined for the flows that are part of your plan.

NOTE: You cannot create parameters through Plan View. You must create the parameters within the flows that are part of your plan. After they are created, they are available for overrides through Plan View.

NOTE: In a plan, parameters and their overrides apply only to the flow task from where they are sourced. They do not apply to other flow tasks. They do not apply back to the source flows.

Tip: To pass a flow parameter value from one recipe to another, you can insert the parameter value in a column in a recipe, export the results as a reference dataset, and then ingest that reference into another flow.


Columns:

Tip: To override the inherited value for the parameter, click the Pencil icon. Then, click Save. Whenever the flow is executed as part of this current plan, the override value is used to replace the parameter value and any override that are defined within the flow.
