  The SAP error message SWF_HTTP013 indicates that there is an issue with the execution of a workflow that involves ABAP reference types. This error typically arises when a workflow is trying to use an ABAP reference type in a context that does not support it, such as when the workflow is executed in a non-ABAP environment or when the execution server does not support the specific reference type being used.

  Modify Data Types: Change the data types in the workflow to use basic types (like structures or simple data types) instead of reference types.
  Check Execution Server: Ensure that the execution server is correctly configured and capable of handling the types being used in the workflow.
  Debugging: Use transaction SWI1 (Workflow Log) to analyze the workflow instance and identify where the error occurs. This can provide insights into which specific reference type is causing the issue.
  Consult Documentation: Refer to SAP documentation or notes related to the specific version of SAP you are using, as there may be known issues or patches available.
