Using parameters in Access Policy transformations

You can use parameters as a placeholder for a value or values in an Access Policy transformation. You define the value of the parameter when you configure the mapping task.

Use the following types of IDs when using parameters in an Access Policy transformation:

•The Consumer User field accepts IDs of users with the Data Marketplace User role.
•The Usage Context field accepts IDs of usage contexts available in Data Marketplace.

For more information about how to fetch user IDs and usage context IDs from Data Marketplace, see Manage requests, orders and consumer accesses.

•The Data Asset field accepts IDs of Data Governance and Catalog data assets.

For more information about how to fetch asset IDs, see List assets in the catalog.
