  • What is the cause and solution for SAP error message VMP_MSG349 - Cannot create non-visual component with phantom as material ?

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


    SAP Error Message:

    VMP_MSG349: Cannot create non-visual component with phantom as material


    Cause:

    This error occurs in the SAP Variant Configuration (LO-VC) or in the context of the SAP Variant Management when the system tries to create a non-visual component (a component that is not displayed in the bill of materials or the product structure) but the component's material is set as phantom.

    • Phantom materials are typically used to represent logical groupings or subassemblies that do not physically exist as separate items but are used for structuring BOMs.
    • Non-visual components are components that are not shown in the product structure or BOM explosion but are used internally for configuration or calculation purposes.
    • The system does not allow a non-visual component to be assigned a phantom material because phantom materials inherently imply a visible grouping in the BOM structure.

    Explanation:

    • Phantom materials are meant to be exploded in the BOM and are visible in the product structure.
    • Non-visual components are meant to be hidden and not appear in the BOM.
    • Assigning a phantom material to a non-visual component contradicts these definitions, causing the system to throw this error.

    Solution:

    To resolve this error, you need to ensure that:

    1. Change the material type of the component:

      • If the component is intended to be non-visual, do not assign a phantom material to it.
      • Use a standard material or a material type that is allowed for non-visual components (e.g., a standard material or a dummy material).
    2. Adjust the component visibility:

      • If the component must be phantom, then it should be set as a visual component (visible in the BOM).
      • Change the component's visibility flag accordingly in the BOM or configuration model.
    3. Review BOM and configuration model:

      • Check the BOM and variant configuration model to ensure consistency between component visibility and material type.
      • Correct any inconsistencies where phantom materials are assigned to non-visual components.

    Related Information:

    • Phantom materials are used to simplify BOMs by grouping components logically without creating separate stock items.
    • Non-visual components are often used in variant configuration to represent internal calculation or configuration elements that should not appear in the final BOM.
    • This error is common in complex variant configuration scenarios where BOMs and configuration models are tightly integrated.
    • SAP Note or documentation related to LO-VC and BOM handling may provide additional guidance.
    • Transaction codes to check BOMs: CS03 (Display BOM), CS02 (Change BOM).
    • Variant Configuration transactions: CU50 (Configuration Profile), CU41 (Class Maintenance).

    Summary:

    Aspect Explanation
    Error Cause Non-visual component assigned a phantom material (not allowed).
    Solution Use a standard material for non-visual components or make the component visual if phantom material is required.
    Check BOM component visibility and material type consistency.

    If you need help with specific steps to change the component visibility or material type, please provide more details about your configuration scenario.
