  • What is the cause and solution for SAP error message KK304 - Cost estimate & already exists ?

    The SAP error message KK304 ("Cost estimate & already exists") typically occurs when you attempt to create a new cost estimate for a material or product that already has an existing cost estimate in the system. This can happen in various scenarios, such as when you are trying to create a cost estimate for a material that has already been costed in the past or when you are trying to create a new version of a cost estimate without properly managing existing ones.

    Cause:

    1. Existing Cost Estimate: The primary cause of this error is that a cost estimate for the specified material already exists in the system.
    2. Costing Version: You may be trying to create a cost estimate in a version that is already in use or has been finalized.
    3. Date Issues: The date of the new cost estimate may overlap with the validity period of an existing cost estimate.
    4. Costing Type: The costing type you are using may not allow for the creation of multiple estimates for the same material.

    Solution:

    1. Check Existing Cost Estimates: Use transaction code CK13N (Display Cost Estimate) to check if a cost estimate already exists for the material in question. If it does, you may need to modify or use the existing estimate instead of creating a new one.

    2. Change Costing Version: If you need to create a new cost estimate, consider using a different costing version that does not conflict with existing estimates.

    3. Delete or Archive Old Estimates: If the existing cost estimate is no longer needed, you can delete or archive it, provided you have the necessary permissions and it complies with your organization's policies.

    4. Adjust Validity Dates: Ensure that the validity dates of the new cost estimate do not overlap with those of existing estimates.

    5. Consult Documentation: Review SAP documentation or consult with your SAP support team for specific guidelines related to cost estimates in your organization.

    Related Information:

    • Transaction Codes: Familiarize yourself with relevant transaction codes such as CK11N (Create Cost Estimate), CK13N (Display Cost Estimate), and CK24 (Delete Cost Estimate).
    • Costing Types: Understand the different costing types and their implications on cost estimates.
    • Costing Variants: Review the configuration of costing variants in your SAP system, as they can affect how cost estimates are created and managed.
    • User Permissions: Ensure that you have the necessary permissions to create, modify, or delete cost estimates in the system.

    If the issue persists after trying the above solutions, it may be beneficial to consult with your SAP support team or a functional consultant who specializes in controlling (CO) and costing processes.
