• What is the cause and solution for SAP error message W3_TOOL105 - No WML cards defined in the dynpro ?

  SAP Error Message:
  
  W3_TOOL105 No WML cards defined in the dynpro
  
  Cause:
  This error occurs when a Web Dynpro application or component tries to render a screen (dynpro) that does not have any WML (Wireless Markup Language) cards defined. In other words, the dynpro is expected to contain WML cards for mobile device rendering, but none are found.
  WML cards are essential for rendering content on WAP-enabled devices or mobile browsers that use WML. If the dynpro is designed for WML output but lacks these cards, the system cannot generate the appropriate markup, leading to this error.
  
  When does it occur?
  
  When accessing a Web Dynpro application/component intended for mobile devices.
  When the dynpro screen is expected to have WML cards but they are missing.
  Possibly during runtime when the system tries to render the screen for a WML-capable device.
  
  
  Solution:
  
  
  Define WML Cards in the Dynpro:
  
  Open the Web Dynpro component in the Web Dynpro Explorer.
  Navigate to the relevant view or window.
  Check the layout and ensure that WML cards are defined for the dynpro.
  If missing, create and assign the necessary WML cards to the dynpro.
  
  
  
  Check Device Configuration:
  
  Verify that the device or browser accessing the application is correctly identified.
  If the device is not WML-capable, ensure the application serves the appropriate content type (e.g., HTML instead of WML).
  
  
  
  Adjust Application Logic:
  
  If the application is not intended for WML devices, adjust the logic to prevent WML rendering.
  Alternatively, provide fallback screens or content for non-WML devices.
  
  
  
  Transport and Deployment:
  
  Ensure that the WML cards are transported correctly between systems.
  Sometimes, missing WML cards in the target system cause this error.
  
  
  
  
  Additional Information:
  
  WML (Wireless Markup Language): A markup language used for devices with limited display capabilities, such as early mobile phones.
  Web Dynpro for Mobile: SAP technology to develop applications for mobile devices, often requiring WML cards.
  Dynpro: A screen or dialog program in SAP GUI or Web Dynpro.

  Summary:
  
  The error W3_TOOL105 No WML cards defined in the dynpro means the system expected WML cards in the dynpro for mobile rendering but found none. The fix is to define the required WML cards in the dynpro or adjust the application/device configuration to avoid WML rendering when not applicable.
