Issue with Dependent DFF Fields in Create Journals – PO Number and Vendor Name

Hi Team,

We have created two Descriptive Flexfields (DFFs) under the Journals tab in the Create Journals task page:

• PO Number
• Vendor Name

Our requirement is to make these fields dependent, such that when a PO Number is selected, the Vendor Name should either:

• Display a List of Values (LOV) filtered based on the selected PO Number, or
• Auto-populate based on the selected PO Number.

Currently, both DFFs are using Table Value Sets to pull the required details. However, we are unable to configure a dependency between these two DFF fields, and the Vendor Name LOV is not getting restricted or populated based on the selected PO Number.
