Study Notes

Flow.BI Variables

  • Variables in Flow.BI act as placeholders or user-defined elements storing data values for use within reports, providing flexibility and reusability.
  • They facilitate dynamic content, calculations, and data filtering, crucial for parameterized reports and customizations.
  • System variables, variables defined using the @ syntax in queries, and variables defined using the {} syntax in expressions are available.
  • Pre-registered variables, system variables, and variables defined using @ syntax in queries and {} syntax in expressions also exist.

Key Features

  • Dynamic Values: Variables hold user-provided inputs, calculated results, or data source values for dynamic reports.
  • Reusable: Consistent values referenced repeatedly reduce redundancy.
  • Parameter Support: Function as report parameters enabling user control over data filtering during runtime.
  • Data Type Flexibility: Support various data types (numbers, strings, dates, booleans, etc.).

Variable Types

  • Static: Fixed values unchanging during execution (e.g., company name).
  • Dynamic: Values that change based on user input, queries, or calculations during execution (e.g., current date, data range).

Common Use Cases

  • User Input: Store user-provided values (date ranges, IDs) to filter report data.
  • Data Calculation: Store intermediate calculation results for broader report use.
  • Text Replacement: Insert dynamic content (usernames, report titles) into text fields.
  • Data Filtering: Establish criteria for filtering data from external sources or queries.
  • Conditional Formatting: Define thresholds or criteria for conditional formatting of report elements.

Setting Up Variables

  • Access the Dictionary panel in the report designer.
  • Navigate to the Variables section and create a new variable.
  • Specify the variable's name, type, default value, and optional settings (e.g., "Request from User").

Using Variables in Reports

  • Variables are inserted into text components, expressions, or filters using the syntax {VariableName}.
  • Example: {ReportTitle} displays the value of the ReportTitle variable.

Variable Binding and Access

  • Variables can be linked to user inputs or external data sources for dynamic functionalities.
  • Variables can be accessed and manipulated within scripts or expressions for advanced logic.

Example Scenarios

  • Parameterized Report: A StartDate variable (Date type), marked as "Request from User", lets users filter sales data using the query SELECT * FROM Sales WHERE SaleDate >= @StartDate.
  • Dynamic Title: A ReportTitle variable with the value "Monthly Sales Report", displayed as {ReportTitle} in a text box.

Benefits of Using Variables

  • Enhanced Interactivity: Enables user-defined filters and parameters.
  • Improved Maintainability: Centralizes control over report values.
  • Support for Complex Logic: Enables complex calculations, conditional statements, and advanced customization.
