Help that can see the screen you are stuck on
A browser extension beside Business Central that reads the page in front of you (the record, the fields, the error it is showing) and answers there, instead of sending you to a manual.
Bring it a problem
The invoice that will not post
It reads the error verbatim, finds the field the error actually means, and traces it back to the setup that caused it, then points at it on the page you already have open.
Why is this date wrong
Posting date, document date, due date and the payment terms behind them. It reads the record in front of you rather than describing how the fields work in general.
Where is this set up
The question that otherwise becomes an email to us and a day of waiting. It names the page, the field and its current value in your own UI language.

What it did
- Read the errors on the page · 1 validation error
- Read the invoice · Payment Terms Code is empty
- Looked up Customer (18) 10000 · no payment terms on the card
- Highlighted Payment Terms Code
Posting is blocked because Payment Terms Code is empty, and Business Central will not post a sales document without one. It is empty because the customer card for Kolding Byg ApS has no payment terms either, so there was nothing to copy in when the invoice was created. Set it here to post now. Every other invoice for this customer uses 14 dage netto.

Four senses the portal assistant does not have
- Where you are
Environment, company, page and record
Including whether the page is in edit mode. It always says what it is looking at, so an answer about the wrong record is visible as the wrong record.
- What the page holds
Every visible field with its caption and value
A structured snapshot: what is required, what can be edited, plus the lines, open dialogs, validation errors and notifications.
- Your own permissions
The session you are already signed into
It reads through the browser session you are in and your own Business Central connection. It cannot see a company you cannot see, and it does not change a field unless the conversation's permission mode allows it.
Put it on the page that keeps generating tickets
The honest test is the error your team has already emailed us about twice.
