• What is the cause and solution for SAP error message WGDS_PROCESS123 - Changes of structure are not permited ?

  The SAP error message:
  WGDS_PROCESS123: Changes of structure are not permitted
  
  Cause:
  This error occurs when you attempt to make changes to the structure of a document or object in SAP Workflow that is not allowed at that point in time. Specifically, in the context of SAP Workflow (often related to the Business Object Repository or workflow container elements), the structure of certain objects or container elements is locked or fixed once the workflow or process has been created or activated.
  Typical scenarios include:
  
  Trying to modify the structure of a workflow container element after the workflow has been activated.
  Attempting to change the definition of a Business Object or its methods/events that are already in use.
  Modifying the structure of a task or workflow element that is currently in use or released.
  
  
  Solution:
  
  
  Check the status of the workflow or object:
  
  Ensure that the workflow is not active or released. You can only change the structure of container elements or objects in the design phase (before activation).
  If the workflow is active, you need to deactivate it first before making structural changes.
  
  
  
  Deactivate the workflow:
  
  Go to the Workflow Builder (transaction SWDD).
  Open the workflow.
  Deactivate the workflow (menu: Workflow -> Deactivate).
  Make the required structural changes.
  Reactivate the workflow.
  
  
  
  Check for locks or transport requests:
  
  Sometimes, the object might be locked by another user or assigned to a transport request.
  Make sure you have the necessary authorizations and the object is not locked.
  
  
  
  If changes are to Business Object structure:
  
  Use transaction SWO1 to modify the Business Object.
  Ensure the object is not in use or locked.
  If the object is in use, consider creating a new version or a new object.
  
  
  
  Consult SAP Notes:
  
  Sometimes, specific SAP Notes address issues related to workflow container or object structure changes.

  Common Restrictions:
  
  Structural changes are generally not allowed on active workflows or objects in productive use.
  Always perform structural changes in a development or test environment before transporting to production.
  
  
  
  
  Summary:
  The error WGDS_PROCESS123 indicates that you are trying to change the structure of a workflow or object that is currently locked or active. To resolve it, deactivate the workflow or object, make the changes, and then reactivate it. Ensure you have the necessary authorizations and that no locks or transports are blocking the changes.
