• What is the cause and solution for SAP error message S_UNIFIED_CON059 - URL too long ?

  The SAP error message S_UNIFIED_CON059 with the description "URL too long" typically occurs when the URL generated by the SAP system exceeds the maximum length allowed by the web browser or the web server. This can happen in various scenarios, such as when using SAP Fiori applications, SAP Gateway services, or when navigating through complex transactions that generate lengthy URLs.
  Causes:
  
  Excessive Query Parameters: The URL may contain too many query parameters or excessively long parameter values.
  Deep Navigation: Navigating through multiple layers of applications or transactions can lead to a long URL.
  Session Information: If session information is appended to the URL, it can contribute to its length.
  Data Volume: Large datasets being passed in the URL can also lead to exceeding the length limit.
  
  Solutions:
  
  Reduce Query Parameters: Simplify the URL by reducing the number of query parameters or their lengths. This may involve changing how data is passed to the application.
  Use POST Instead of GET: If applicable, switch from using GET requests (which append data to the URL) to POST requests (which send data in the request body). This can significantly reduce URL length.
  Session Management: Ensure that session management is handled properly, and avoid passing session-related data in the URL.
  URL Shortening: If possible, implement URL shortening techniques or use identifiers instead of full data values.
  Check Configuration: Review the configuration settings of the web server or application server to see if there are any limits set on URL length and adjust them if necessary.
  Fiori Launchpad Configuration: If using Fiori, check the launchpad configuration and ensure that the navigation is optimized to avoid deep links.
  
  Related Information:
  
  Browser Limitations: Different browsers have different maximum URL lengths (typically around 2000 characters for most browsers).
  Web Server Limitations: Web servers (like Apache, Nginx, etc.) may also impose their own limits on URL length.
  SAP Notes: Check SAP Notes for any specific patches or updates related to this error. SAP frequently releases updates that may address known issues.
  Debugging Tools: Use browser developer tools to inspect the network requests and see the exact URL being generated, which can help identify the cause of the length issue.
