Adding a FlowField

FlowFields are fields that are not actually stored in the database. They are calculated fields that the user can call instead of performing the calculations themselves. This recipe will show you how to add a FlowField to your tables.

How to do it...

  1. Follow the steps from the Creating a table recipe to create a table.

  2. Add the following field to the table:

    Field no.

    Field name

    Data type

    Length

    10

    Sell-to Customer No.

    Code

    20

  3. View the properties for this field (Shift + F4).

  4. Set the following properties:

    Property

    Value

    FieldClass

    Flowfield

    CalcFormula

    Lookup("Sales Invoice Header"."Sell-to

    Customer No." WHERE (No.=FIELD(Document No.)))

    Editable

    No

  5. Close the Properties window.

  6. Save and close the table.
