• What is the cause and solution for SAP error message ECATT_WDR_EN022 - URL contains duplicate parameter(s). ?

  The SAP error message ECATT_WDR_EN022 indicates that there are duplicate parameters in the URL being used in an eCATT (extended Computer Aided Test Tool) script. This error typically arises when the same parameter is included multiple times in the URL, which can lead to confusion in processing the request.
  Cause:
  
  Duplicate Parameters: The URL being constructed or used in the eCATT script contains the same parameter name more than once. For example, a URL like http://example.com?param1=value1&param1=value2 would trigger this error because param1 is specified twice.
  Incorrect Script Logic: The logic in the eCATT script may inadvertently append the same parameter multiple times due to loops or incorrect variable handling.
  Dynamic URL Generation: If the URL is being generated dynamically based on certain conditions, it may lead to duplicates if not properly managed.
  
  Solution:
  
  Review the URL: Check the URL being used in the eCATT script for any duplicate parameters. Ensure that each parameter is unique.
  Modify the Script: If the script is generating the URL dynamically, modify the logic to prevent the same parameter from being added multiple times. This may involve checking if a parameter already exists before appending it.
  Use Unique Parameter Names: If you need to send multiple values for the same parameter, consider using a different naming convention or structure (e.g., param1=value1&param1=value2 can be changed to param1_1=value1&param1_2=value2).
  Debugging: Use debugging tools or logs to trace how the URL is being constructed and identify where the duplication is occurring.
