This is what happens in the video
In Business Central you can click your way from a summary number directly to the underlying records. The blue fields on cards like the customer card and item card are called flow fields, and they act as live links into the detailed data behind them.
If you click the Balance (LCY) field on a customer card, you open the customer ledger entries that make up that balance. On an item card, clicking the quantity on sales orders opens the full list of sales orders containing that item.
Flow fields are not editable on their own. They calculate their value from the records below them, so the number you see always reflects the current detail.
What flow fields are in Business Central
When you look at a customer card in Business Central, you will notice that some fields are blue. You see them both in the direct fields on the card and out in the fact box on the right side. These blue fields are called flow fields.
A flow field does not store a value of its own. Instead, it calculates and displays a value based on the information that sits below it, such as ledger entries or document lines. The blue colour tells you the field is clickable and that it links to that underlying data.
How to navigate from a flow field to the underlying data
When you click a flow field, Business Central takes you to the records that make up the number. The field drills down into the detailed information behind it.
For example, on the customer card you can click the Balance (LCY) field. This opens all the customer ledger entries for that customer, so you can see exactly which transactions add up to the balance shown.
Using flow fields on the item card
The same principle applies on the item card. From an item card you can see, for instance, how many units of the item are tied up on sales orders.
If you click that number, you get the full list of all the sales orders where the item has been entered. This makes it easy to go from a single aggregated figure straight to the documents behind it, without searching through reports or lists manually.
