• What is the cause and solution for SAP error message WS_TOOL191 - Provide display name ?

  SAP Error Message:
  
  WS_TOOL191: Provide display name
  
  Cause:
  The error message WS_TOOL191: Provide display name typically occurs in SAP Workflow or Web Dynpro applications when a required display name or description field is missing or not provided. This usually happens during the configuration or execution of a workflow step, task, or UI element where a display name is mandatory but has been left blank.
  In other words, the system expects a "display name" attribute for a particular object (such as a workflow step, container element, UI control, or tool) but finds it empty or undefined.
  
  When does it occur?
  
  While designing or modifying SAP Business Workflow tasks or steps.
  During the configuration of Web Dynpro components or UI elements.
  When creating or editing workflow container elements or binding parameters.
  In some cases, during transport or import of workflow objects if display names are missing.
  
  
  Solution:
  
  
  Provide the Display Name:
  
  Identify the object (workflow step, task, container element, UI control, etc.) that triggers the error.
  Open the relevant configuration or design tool (e.g., Workflow Builder, Web Dynpro Component Editor).
  Locate the field labeled "Display Name," "Description," or similar.
  Enter a meaningful display name or description.
  Save and activate the object.
  
  
  
  Check Workflow Container Elements:
  
  If the error occurs in workflow container elements, ensure that each container element has a proper description or display name.
  Use transaction PFTC (for tasks) or SWDD (Workflow Builder) to check and maintain these elements.
  
  
  
  Verify UI Elements in Web Dynpro:
  
  If related to Web Dynpro, open the component in the Web Dynpro Explorer.
  Check the properties of UI elements or context nodes for missing display names.
  Provide the required display name.
  
  
  
  Transport and Import Checks:
  
  If the error appears after transport, verify that all objects were transported correctly.
  Sometimes, missing display names can be due to incomplete transport or inconsistencies.
  
  
  
  SAP Notes and Support:
  
  Check SAP Notes for any known issues related to WS_TOOL191.
  If the problem persists, consider raising a support ticket with SAP, providing details of the object and context.
