Redwood Receiving Display Calculated Read Only Field on Orders to Receive Page

Hi Team,

We are using Oracle Fusion SCM Procurement – Redwood UI, specifically Receiving > Orders to Receive > Receive with Details.

Requirement:
Display a read-only, user-visible field (e.g., Available Quantity) that dynamically calculates
Remaining Quantity – Receipt Quantity.
This field is for display only and does not need to be stored.

What we tried:

• Created a custom field and calculation logic in OrdersToReceiveAdvReceiver layout
• Created a custom read-only template and duplicated the seeded rule set
• However, on the Orders to Receive page, clicking Rules redirects to Page Designer, where the layout is seeded and locked
• The custom field added at the layout level is not visible on the page
