    You should be able to Personalize those fields onto the Page.  If you can't see it in Personalize, or if you want to make it visible for an entire Profile, you can select the Profile and Configure to add any field from the table.

    When doing your Personalize or Configure, be sure to click into the Sales Lines, otherwise you will only see the fields for the Sales Header and not the Sales Lines.

    Try modify() and altering the visible property of the fields in the page extension. Also worth checking what application area they are part of as standard. I expect it is Jobs which means certain profiles don’t see it

    Hello,
     
    You can change Field("Job No."; rec."Job No.) to Field("Job No.1"; rec."Job No.) and add caption Property as 'Job No.' This way you can resolve this error.

    Hello,

    To make the "Job No." and "Job Task No." fields visible in the Sales Invoice Subform in Microsoft Dynamics 365 Business Central, you can create a Page Extension in AL. These fields are typically hidden by default, but you can modify their visibility by setting the Visible property to true.

    Here's an example of how you can achieve this:

    Yes, basically the Job No. and Job Task No. fields are already available on the Sales Line subform, but they are set with Visible = false. To make them usable, you just need to extend the page and modify the Visible property of these fields to true.
     
    pageextension 50100 "Sales Line Ext. Show Job Fields" extends "Sales Order Subform"
{
    layout
    {
        modify("Job No.")
        {
            Visible = true;
        }
        modify("Job Task No.")
        {
            Visible = true;
        }
    }
}
     
    Once they’re visible, you should be able to Personalize and add them to the page. If they still don’t appear during personalization, or if you want to make them visible for all users under a specific profile, go to the Profile and use Configure to add the fields from the table.

    It's available within Standard, no need to worry to make it even visible on SO PO. Personalize and add it as we normally do, regarding making it available globally, you have to configure it, from the profile screen it's achievable.

    It's standard Fields—just personalize the SO/PO to show it. For all users, configure it via profile settings. 
    You can consider customization by modifying field property to visible true
