Customize DFF value based on standard field on 'Request a New Position' page

Summary:

Seeking guidance on referencing a standard field in a DFF value set customization.

Content (required):

In the Oracle Fusion application, I am navigating through the path: Client Groups -> Workforce Structure -> Request a New Position -> Continue -> Continue. My objective is to customize a Descriptive Flex Field (DFF) based on the value of a standard field, specifically the 'Department' field.

Traditionally, for DFF customization based on another DFF, I utilize the :{VALUESET.<VALUESET_CODE>} syntax in the value set query, especially in the WHERE conditions. However, I'm uncertain about the method or bind variable to reference the standard 'Department' field in the value set query for a similar customization.
