  • What is the cause and solution for SAP error message TK584 - Cannot change task type to "Unclassified" ?

    The SAP error message TK584, which states "Cannot change task type to 'Unclassified'," typically occurs in the context of SAP Project System (PS) or SAP Controlling (CO) when there is an attempt to change the task type of a project task or activity to "Unclassified." This error can arise due to various reasons, and understanding the cause and potential solutions is essential for resolving the issue.

    Cause:

    1. Task Type Restrictions: The system may have restrictions on changing certain task types based on the current status of the task or project. For example, if the task is already assigned to a specific type or has dependencies, it may not allow changing to "Unclassified."

    2. Project Structure: The project structure may not support unclassified tasks. If the project is set up in a way that requires specific task classifications, changing to "Unclassified" may violate these rules.

    3. Authorization Issues: The user may not have the necessary authorizations to make changes to task types, especially if the project is in a locked state or if there are specific roles assigned.

    4. System Configuration: There may be configuration settings in the SAP system that prevent changing task types to "Unclassified." This could be due to project type settings or other related configurations.

    Solution:

    1. Check Task Status: Review the current status of the task. If it is in a completed or locked state, you may need to unlock it or change its status before attempting to change the task type.

    2. Review Project Structure: Ensure that the project structure allows for unclassified tasks. If necessary, consult with your project manager or SAP administrator to understand the project requirements.

    3. Authorization Check: Verify that you have the necessary authorizations to change task types. If not, contact your SAP security administrator to request the appropriate permissions.

    4. Consult Configuration Settings: If you have access to the configuration settings, check if there are any restrictions on task types for the specific project type you are working with. Adjustments may need to be made by a system administrator.

    5. Use Alternative Task Types: If changing to "Unclassified" is not possible, consider using an alternative task type that meets your needs without violating system rules.

    6. SAP Notes and Documentation: Check for any relevant SAP Notes or documentation that may provide additional insights or updates regarding this error message. SAP's support portal can be a valuable resource.

    Related Information:

    • SAP Project System (PS): Understanding the structure and types of tasks within SAP PS can help in managing projects effectively.
    • SAP Authorization Concepts: Familiarity with how authorizations work in SAP can help prevent issues related to permissions.
    • SAP Community and Forums: Engaging with the SAP community can provide insights from other users who may have encountered similar issues.
