Custom Unbound DAC Extension Fields Not Displaying in Mobile App (EP301020 - Expense Receipts) in 25R2

Hi Everyone,

I am working on Acumatica 25R2 and have added three custom unbound DAC extension fields to the Expense Receipts (EP301020) screen.

[PXDecimal]
[PXUIField(DisplayName = "...", Enabled = false)]
public decimal? UsrReceiptLimitPerBaseUnit { get; set; }

[PXDecimal]
[PXUIField(DisplayName = "...", Enabled = false)]
public decimal? UsrMaxReceiptLimit { get; set; }

[PXDecimal]
[PXUIField(DisplayName = "...", Enabled = false)]
public decimal? UsrReceiptLimitDifference { get; set; }

These fields are calculated in a graph extension and display correctly in the web UI. They are added to the ASPX page under a custom group called Receipt Limit Details.

I am now trying to display the same fields in the Acumatica Mobile App.

I updated the Mobile Application customization with:

update screen EP301020 {

    update container "ClaimDetails" {

        add group "ReceiptLimitDetails" {
            displayName = "Receipt Limit Details"
            collapsable = True
            collapsed = True
            template = ExpansionPanel

            add field "ClaimDetails#UsrReceiptLimitPerBaseUnit"
            add field "ClaimDetails#UsrMaxReceiptLimit"
            add field "ClaimDetails#UsrReceiptLimitDifference"
        }
    }
}

The customization publishes successfully with no errors.

I verified that:

• The new Receipt Limit Details group appears when I add a standard field like UnitCost.
• However, my custom fields do not appear in the mobile app.
• I had to type the custom field names manually because they do not appear in the Mobile Application field suggestions.
• The fields are available and working correctly in the browser.

My questions

1. Does the Acumatica Mobile App support unbound DAC extension fields on EP301020?
2. Is there an additional step required to expose custom DAC extension fields to the Mobile Application metadata?
3. Do these fields need to be added to a Web Service Endpoint or Mobile Endpoint before they can be used?
4. Has anyone successfully displayed calculated unbound fields in the Mobile App for Expense Receipts?

Any guidance or examples would be greatly appreciated.

Thank you!
