  • What is the cause and solution for SAP error message WTYMP018 - Message type &1 not allowed ?

    Certainly! Here's a detailed explanation for the SAP error message:


    SAP Error Message: WTYMP018 - Message type &1 not allowed


    1. Cause

    The error message WTYMP018 occurs when a message type that is not allowed or not defined for a particular process or object is being used. Specifically, in the context of SAP Workflow or message processing, this means that the system encountered a message type (represented by &1) which is not permitted in the current scenario.

    Common causes include:

    • Attempting to send or process a message type that is not configured or allowed in the workflow or message type customizing.
    • Using an incorrect or undefined message type in a workflow step or communication.
    • Custom developments or enhancements trying to trigger a message type that is not registered or allowed.

    2. Solution

    To resolve the error:

    • Check the message type: Identify the message type passed in the error message (the placeholder &1 will be replaced by the actual message type in the system log or dump).

    • Verify configuration:

      • Go to the relevant customizing transaction (e.g., for workflow message types, use transaction SWDD or SWU3).
      • Check if the message type is defined and allowed for the object or process you are working with.
      • For workflow, verify the message type in the workflow container and ensure it is correctly linked to the workflow tasks or events.
    • Adjust or add the message type:

      • If the message type is missing, add it to the allowed list or define it properly.
      • If the message type is incorrect, correct the code or configuration to use a valid message type.
    • Check custom code:

      • If the error arises from custom developments (user exits, BAdIs, or custom workflow steps), review the code to ensure only valid message types are used.
    • Transport and system consistency:

      • Ensure that the message type definitions and workflow configurations are consistent across systems (development, quality, production).

    3. Related Information

    • Transaction Codes:

      • SWDD – Workflow Builder (to check workflow definitions and message types)
      • SWU3 – Workflow Customizing (to check workflow configuration)
      • SWE2 – Message Type Customizing (to check and maintain message types)
    • SAP Notes and Documentation:

      • Check SAP Notes related to workflow message types or the specific module you are working with.
      • Review SAP Help Portal documentation on Workflow and message types.
    • Debugging:

      • Use transaction ST22 to check dumps if the error causes a short dump.
      • Use transaction SM21 or SLG1 to check system logs for more details.
