DFF Required to Cover Cost Center and Natural Account Segments in Expense Item

We require a Descriptive Flexfield (DFF) to capture and auto-populate both the Cost Center and Natural Account segments. The logic should be as follows:

1. Cost Center should be auto-populated based on the selected Project.
2. Natural Account should be auto-populated based on the selected Expense Type.

Please check and provide the steps to configure the same in the instance. Thank you in advance.

Thanks,

Prathish.
