How to add a text box to create expense screen- Receipt Missing Ack

Hi Team,

Could you please let us know the recommended approach to add a text box for “Receipt Missing Acknowledgement” at the Expense Item level on the Oracle Fusion Create Expense screen, specifically for scenarios where users forget to attach receipt details?

Our expectation is that users should be prompted to provide a justification or acknowledgement when a receipt is missing, preferably through a standard and supported configuration (for example, using Expense Item Descriptive Flexfields and expense rules).

Kindly share the step-by-step details or configuration guidance to implement this requirement.

Thanks in advance for your support.

Regards,
Vasu
