• What is the cause and solution for SAP error message SWRD225 - Container element '&' refers to object type & -> a conversion takes place ?

  The SAP error message SWRD225 indicates that there is a problem with a container element in a workflow. Specifically, it refers to a situation where a container element is trying to reference an object type, and a conversion is taking place. This typically occurs in the context of SAP Business Workflow, where data types and object references need to be correctly aligned.
  Cause:
  
  Type Mismatch: The container element is defined with a specific data type, but the object type it is trying to reference does not match this data type. This can happen if the workflow is expecting a certain type of object (e.g., a business object) but is receiving a different type.
  Incorrect Mapping: The mapping of the container element to the object type may not be correctly set up, leading to a conversion attempt that fails.
  Changes in Object Types: If there have been changes to the object types or the definitions of the container elements after the workflow was created, this can lead to inconsistencies.
  
  Solution:
  
  Check Container Definitions: Review the definitions of the container elements in the workflow. Ensure that they are correctly defined and that the data types match the expected object types.
  Adjust Object Type References: If the object type has changed, update the references in the workflow to point to the correct object type.
  Review Workflow Steps: Go through the workflow steps where the error occurs and ensure that the data being passed between steps is compatible and correctly mapped.
  Test the Workflow: After making changes, test the workflow to ensure that the error is resolved and that the workflow functions as expected.
  Consult Documentation: If necessary, refer to SAP documentation or help resources for specific guidance on the object types and container elements you are working with.
