Smart SAP Assistant

• What is the cause and solution for SAP error message WK312 - Preview could not be loaded ?

  The SAP error message WK312: Preview could not be loaded typically occurs in the context of SAP Workflow when trying to preview a workflow definition or workflow container elements in the Workflow Builder or related tools.
  
  Cause
  
  Missing or incorrect configuration: The workflow preview relies on certain configuration and metadata to display the workflow steps and container elements. If these are missing or inconsistent, the preview cannot be generated.
  Authorization issues: The user may lack the necessary authorizations to access the workflow objects or related repository objects.
  Transport or system inconsistencies: If the workflow objects were transported incorrectly or the system is missing some workflow-related components, the preview might fail.
  SAP GUI or frontend issues: Sometimes, the SAP GUI or the workflow builder tool might have issues rendering the preview due to frontend problems.
  Corrupted workflow objects: If the workflow definition or container elements are corrupted or incomplete, the preview cannot be loaded.
  
  
  Solution
  
  
  Check authorizations
  
  Ensure the user has the necessary authorizations for workflow development and display, such as:
  
  S_WF_WI (Workflow: Work Item)
  S_WF_BPM (Workflow Builder)
  S_DEVELOP (Development objects)
  
  
  
  Verify workflow object consistency  
  
  Use transaction SWU3 (Automatic Workflow Customizing) to check and fix workflow customizing.
  Use transaction SWI1 or SWI2_FREQ to check workflow logs and identify issues.
  Re-import or re-transport the workflow objects if they are inconsistent or corrupted.
  
  
  
  Check workflow container elements  
  
  Open the workflow in the Workflow Builder (transaction SWDD) and verify that all container elements are correctly defined.
  If container elements are missing or incorrectly defined, correct them.
  
  
  
  Clear SAP GUI cache and restart  
  
  Sometimes, GUI cache issues cause display problems. Clear the SAP GUI cache or restart the SAP GUI and try again.
  
  
  
  Check system logs and dumps  
  
  Use transaction ST22 to check for any short dumps related to workflow preview.
  Use transaction SM21 to check system logs for related errors.
  
  
  
  Apply SAP Notes  
  
  Search the SAP Support Portal for notes related to WK312 or workflow preview issues. There might be patches or corrections available.
