Data Fields

In Flow.BI reports, data fields are the columns in your data source that hold information. You can access them to display values in text components.

Referencing Data Fields

To use a data field in a text expression, put its name inside curly braces. Example: {ProductName} will display the product name.

Current Record

When referencing a data field in a text expression, you're always working with the information from the current record being displayed.

Data Band Context

Data bands are sections in a Flow.BI report that display groups of data. Inside a band, you can access data fields from the corresponding group.

Calculations in Text Expressions

You can add calculations to your text expressions using data fields. For example, to calculate total price, you could use: {UnitPrice * Quantity}.

Conditional Formatting

Use conditional expressions (like IF) to show different text based on values in data fields. For example: {IF(Quantity > 10, "High", "Low")} will display "High" for quantities over 10.

How can you use conditional formatting with data fields?

Conditional expressions like IF statements allow you to dynamically display different text based on values in data fields. For example: {IF(Quantity > 10, "High", "Low")} will display "High" for quantities over 10.

Study Notes

Using Data Fields in Flow.BI

  • Data fields are referenced in text expressions using curly braces {}.
  • Example: {Orders.ProductName} displays the "ProductName" from the "Orders" data source.
  • Specify the data source name (Orders in the example) before the field name for clarity, especially with multiple data sources.
  • Data fields are accessible within the context of a data band. This means the data displayed changes as the data record moves within the report.
  • Calculations can be performed directly within expressions, like {Orders.UnitPrice * Orders.Quantity} for total price calculations.
  • Conditional formatting allows displaying different text based on conditions: {If(Orders.Quantity > 10, "High Quantity", "Low Quantity")}.
  • Refer to data fields using the syntax {DataSource.FieldName}.
  • The current record is referenced when using data fields.
  • Typically used in reports with bands for dynamic displays.
  • To reference data fields, enclose the field name within curly braces {}.
  • Example: For a data source "Orders" with fields "ProductName" and "UnitPrice", display fields using:
    • Product Name: {Orders.ProductName}
    • Unit Price: {Orders.UnitPrice}
  • Ensure the correct data source name is used, especially with multiple sources.
  • Data field values are accessible within data bands.
  • Calculations can be performed directly within expressions (e.g., total price).
