    SAP Error Message:

    WS_TOOL087 - Error generating ST &1


    Meaning / Cause:

    • The error WS_TOOL087 occurs during the generation of a Service Task (ST) in SAP Workflow.
    • The placeholder &1 typically contains the name or identifier of the Service Task that failed to be generated.
    • This error usually indicates that the system encountered a problem while trying to create or generate the workflow service task object.
    • Common causes include:
      • Missing or incorrect configuration in the workflow definition.
      • Incomplete or inconsistent data in the workflow repository.
      • Authorization issues preventing the generation of the service task.
      • Transport or system inconsistencies.
      • Issues with the underlying function modules or classes linked to the service task.
      • Problems with the workflow container or binding.

    Possible Causes in Detail:

    1. Incorrect or Missing Workflow Object:

      • The service task references an object or method that does not exist or is incorrectly defined.
    2. Authorization Issues:

      • The user or background job generating the service task lacks necessary authorizations.
    3. Repository Inconsistencies:

      • The workflow repository might be inconsistent or corrupted.
    4. Transport or System Issues:

      • Transport of workflow objects might have failed or been incomplete.
    5. Incorrect Binding or Container Elements:

      • The workflow container elements required for the service task are missing or incorrectly bound.

    How to Analyze:

    • Check the exact service task name or ID in the error message (&1).
    • Review the workflow definition in transaction SWDD or PFTC (for tasks).
    • Verify the service task configuration, including the method or function module it calls.
    • Check the workflow container and binding for correctness.
    • Look for authorization issues for the user or job running the workflow.
    • Review system logs (SM21), short dumps (ST22), and workflow logs (SWI1, SWI2_DIAG).
    • Check for inconsistencies in the workflow repository using transaction SWU_OBUF or SWU3 (Workflow Customizing).

    Solution / Resolution Steps:

    1. Verify Service Task Definition:

      • Go to transaction PFTC.
      • Enter the service task name (from &1).
      • Check if the task is correctly defined with the proper object and method.
    2. Check Workflow Container and Bindings:

      • In transaction SWDD, open the workflow.
      • Verify that the container elements required by the service task are present and correctly bound.
    3. Check Authorizations:

      • Ensure the user or background job has the necessary authorizations to generate and execute workflows.
      • Use transaction SU53 after reproducing the error to check missing authorizations.
    4. Repair Workflow Repository:

      • Run transaction SWU3 to check and fix workflow customizing.
      • Use SWU_OBUF to regenerate the workflow object buffer.
    5. Check for Transport or System Issues:

      • If the workflow or service task was recently transported, verify the transport logs.
      • Reimport or reapply transports if necessary.
    6. Debug or Trace:

      • If the problem persists, enable workflow trace in SWI1 or use debugger to analyze the error during generation.
