A vendor needs to create a Date Difference calculated field.

When creating a Date Difference calculated field in Workday, both dates must exist on the same business object. If they are on different business objects, you need to first bring the second date onto the primary object. To do that, you use a:

Lookup Related Value calculated field — this allows you to retrieve a field (like a date) from a related business object, so it can then be used in further calculations.

Example scenario:

You want to subtract Hire Date (on the Worker object) from Dependent’s Birth Date (on the Dependent object).

These are on different objects → use Lookup Related Value to pull the second date into the current object context.

Then, create the Date Difference using both dates on the same object.

Why other options are incorrect:

B. Build Date creates a synthetic date, not for bridging objects.

C. Lookup Date Rollup rolls up values across multiple related objects, not typically used for 1-to-1 value bridging.

D. Lookup Value as of Date is used for time-sensitive lookups (e.g., point-in-time values), not structural bridging.
