Step 1. Create a crosswalk

Create a crosswalk to map code values in a source code list to code values in a target code list from same or different reference data sets. Value mappings provide a way to translate code values in one code list to code values in another code list. You can specify internal ID and alias for a crosswalk.

Effective in the April 2025 release, the ability to specify a unique internal ID and alias for a crosswalk is available for preview.

Preview functionality is supported for evaluation purposes but is unwarranted and is not supported in production environments or any environment that you plan to push to production. Informatica intends to include the preview functionality in an upcoming release for production use, but might choose not to in accordance with changing market or technical circumstances. For more information, contact Informatica Global Customer Support.

Click

New

and select

Crosswalk

The

New Crosswalk

page appears and displays the

Summary

tab.

You cannot configure the general properties. A crosswalk inherits its general properties from the source and target reference data sets.

In the

Source Reference Data Set

field, select the reference data set that contains the code list you want to map.

In the

From Code List

field, select the source code list.

The crosswalk is associated with the source code list.

In the

Target Reference Data Set

field, select the reference data set that contains the code list you want to map to the selected source code list.

In the

To Code List

field, select the target code list

The target code list contains code values that you want to map.

Configure the additional properties fields.

Crosswalks inherit the name from the reference data set.

The following table lists the properties that you can configure for a crosswalk:

Additional Property Field	Description
Name	Display name of a crosswalk.
Internal ID	Required. Unique identifier of a crosswalk, limited to a maximum of 45 characters. You can use alphanumeric characters and underscores. After you save an asset, you can't edit the internal ID. You can't specify internal IDs for existing assets.
Alias	Alternative identifier for a crosswalk, limited to a maximum of 70 alphanumeric characters. After you save an asset, you can edit the alias.
Description	Short description of the crosswalk. The description cannot exceed 4000 characters.
Confidentiality	Confidentiality level of the code list inherited from the reference data set. The confidentiality levels are confidential, internal, restricted, and public.
Status	State of a crosswalk in the life cycle. If you do not see options in the list, configure your system reference data values. For more information, see Adding values to system reference data.
Effective Date	Date from when the status is effective.
Approved by	User who approved a crosswalk.
Approved on	Date of approval.

Click

Save

A new crosswalk is created. The crosswalk name displays the source code list and target code list. If the target reference data set is different from the source reference data set, the crosswalk name displays the name of the target reference data set adjacent to the target code list.

In the

Explore

panel, you can view the crosswalk name appended with the target reference data set name when the source and target reference data sets are different.

Users with a Reference Data Management Basic Edition license can create crosswalks only between the default code list and another code list of the same reference data set.
