  • What is the cause and solution for SAP error message SWF_HTTP012 - ABAP table types are not supported by the execution server ?

    The SAP error message SWF_HTTP012 indicates that there is an issue with the execution of a workflow that involves ABAP table types. This error typically arises when a workflow is trying to use a data type that is not supported by the execution server, particularly when it comes to ABAP table types.

    Cause:

    1. Unsupported Data Types: The execution server (like a different application server or a non-ABAP server) does not support ABAP-specific data types, such as internal tables or structures.
    2. Workflow Configuration: The workflow might be incorrectly configured to use ABAP table types in a context where they cannot be processed.
    3. Cross-Server Execution: If the workflow is being executed on a server that does not have the same ABAP capabilities as the server where the workflow was defined, this error can occur.

    Solution:

    1. Change Data Types: Modify the workflow to use supported data types. Instead of using ABAP table types, consider using simpler data types that are compatible with the execution server.
    2. Use Workflow Container: If you need to pass complex data structures, consider using a workflow container to encapsulate the data in a way that is compatible with the execution server.
    3. Check Workflow Steps: Review the steps in the workflow to ensure that they are not trying to pass ABAP table types to activities that cannot handle them.
    4. Server Configuration: Ensure that the execution server is properly configured to handle the types of data being passed. If necessary, adjust the server settings or use a different server that supports the required data types.
    5. Debugging: Use transaction SWI1 (Workflow Log) to analyze the workflow instance and identify where the error occurs. This can provide insights into which specific step is causing the issue.

    Related Information:

    • SAP Notes: Check SAP Notes related to SWF_HTTP012 for any specific patches or updates that may address this issue.
    • Workflow Documentation: Review SAP documentation on workflows to understand the limitations and best practices for data types in workflows.
    • Community Forums: Engage with SAP community forums or support channels for additional insights and solutions from other users who may have encountered similar issues.

    By addressing the data type compatibility and ensuring that the workflow is correctly configured, you should be able to resolve the SWF_HTTP012 error.
