• What is the cause and solution for SAP error message SWF_HTTP011 - ABAP structure types are not supported by the execution server ?

  The SAP error message SWF_HTTP011 indicates that there is an issue with the execution of a workflow that involves ABAP structure types. This error typically arises when a workflow is trying to use an ABAP structure that is not supported by the execution server, which can happen in scenarios involving web services or when using certain types of data in workflows.
  Cause:
  
  Unsupported Data Types: The execution server (like a web service or an external system) may not support ABAP structure types. This can occur when the workflow is trying to pass complex data types that are not recognized by the external system.
  Incompatible Workflow Configuration: The workflow may be configured to use data types that are not compatible with the execution environment.
  Incorrect Mapping: There may be an issue with how the data is being mapped between the SAP system and the external system.
  
  Solution:
  
  Use Simple Data Types: Modify the workflow to use simple data types (like strings, integers, etc.) instead of complex ABAP structures. This can often resolve the issue as simple types are more universally supported.
  Check Workflow Configuration: Review the workflow configuration to ensure that it is set up correctly and that the data types being used are compatible with the execution server.
  Data Transformation: If you need to pass complex data, consider transforming the data into a format that is supported by the execution server (e.g., JSON or XML) before sending it.
  Update Workflow Logic: If the workflow logic is using ABAP structures, consider refactoring the logic to avoid using unsupported types.
  Consult Documentation: Refer to SAP documentation for the specific execution server you are using to understand its limitations regarding data types.
