  Error Message
  W3_WIZARD002: Enter a variable for the input field
  
  Cause
  This error occurs when you are working with SAP Web Dynpro or SAP Web Application Designer (WAD) and you are defining or configuring a wizard or a screen where an input field requires a variable to be assigned, but no variable has been provided.
  In other words, the input field in the wizard or screen expects a binding to a context attribute or a variable that holds the data entered by the user. If this binding is missing or not specified, the system raises this error.
  
  When does it typically occur?
  
  When designing a wizard step in Web Dynpro or WAD.
  When creating or modifying input fields in a wizard or screen and forgetting to assign a context attribute or variable.
  When the input field is configured to require a variable for data binding but none is assigned.
  
  
  Solution
  To resolve this error, you need to assign a variable or context attribute to the input field:
  
  
  Open the wizard or screen in the Web Dynpro or WAD editor.
  
  
  Locate the input field that triggers the error.
  
  
  Assign a variable or context attribute:
  
  In Web Dynpro, bind the input field to a context attribute in the component controller or view context.
  In WAD, assign a variable name in the input field properties that corresponds to a parameter or context variable.
  
  
  
  Save and activate your changes.
  
  
  Test the wizard or screen again to ensure the error no longer appears.
  
  
  
  Additional Information
  
  Context Binding: In Web Dynpro, input fields must be bound to context attributes to hold user input. Without this binding, the UI element has no place to store or retrieve data.
  Wizard Steps: Wizards often require variables to pass data between steps. Missing variable assignments break this flow.
  Validation: SAP enforces this to ensure data integrity and proper flow of information in UI components.
