Sometimes users forget to fill in the "Fiscal Invoice Number PAC" field in the Purchase Invoices and since when the invoices are registered they can no longer be modified, I would like to create a page that allows to modify said field of the Posted Purchase Invoice page . Any idea how I could do this? I'm lost

Please look at Update Document Action and extend the page with required field

I do not have that field in my version of Business Central.

But something like this should work:

pageextension 50101 PostedPurchaseInvoiceExt extends "Posted Purchase Invoice"

{

layout

{

modify("Fiscal Invoice Number PAC")

{

Editable = true;

}

}

}

If that field is marked as none editable in the table definition you might have to do a workaround for that.

Hi, I am leaning towards Mohana's solution, for example, I want to add a change to the Payment Term Code in Posted Purchase Invoice.

Add new field to "Posted Purch. Invoice - Update" page.

Source code:

pageextension 50111 MyExtension5 extends "Posted Purch. Invoice - Update" { layout { addafter("Payment Method Code") { field("Payment Terms Code"; Rec."Payment Terms Code") { ApplicationArea = All; } } } } codeunit 50111 MyCodeunit5 { [EventSubscriber(ObjectType::Page, Page::"Posted Purch. Invoice - Update", 'OnAfterRecordChanged', '', false, false)] local procedure OnAfterRecordChanged(var PurchInvHeader: Record "Purch. Inv. Header"; xPurchInvHeader: Record "Purch. Inv. Header"; var IsChanged: Boolean; xPurchInvHeaderGlobal: Record "Purch. Inv. Header"); begin IsChanged := PurchInvHeader."Payment Terms Code" <> xPurchInvHeaderGlobal."Payment Terms Code"; end; [EventSubscriber(ObjectType::Codeunit, Codeunit::"Purch. Inv. Header - Edit", 'OnBeforePurchInvHeaderModify', '', false, false)] local procedure OnBeforePurchInvHeaderModify(var PurchInvHeader: Record "Purch. Inv. Header"; PurchInvHeaderRec: Record "Purch. Inv. Header"); begin PurchInvHeader."Payment Terms Code" := PurchInvHeaderRec."Payment Terms Code"; end; }

Hope this helps.

Thanks.
