  • Message number: 603

  • Message text: Relationship of node &1 to node &2 creates recursion via bill of material

  • Show details Hide details
  • What causes this issue?

    The created or changed relationship of node &V1& to node &V2& creates a
    recursion involving a bill of material.
    The header material of this bill of material is &V3&, the component is
    &V4&.
    One material that you are using in the nodes <(>,<)> is likewise a part
    of a bill of material. As a result, the product structure becomes
    recursive, as follows:
    Either directly by an immediately-assigned other node and its material
    reference in the bill of material, or by a different material in this
    bill of material
    Or indirectly by a different material that exists in the product
    structure and likewise has to be part of a bill of material

    System Response

    The relationship is not created.

    How to fix this error?

    Start the recursivity analysis with the materials you have used in the
    nodes &V1& and &V2&, and check the bills of material <(>,<)> in which
    the materials &V3& und &V4& are used.

This typically occurs when a node (component) in the BOM references another node in such a way that it creates a circular dependency. For example, if component A references component B, and component B references component A, this creates a recursion that the system cannot resolve.
    
    Cause: Circular Reference: The most common cause is a circular reference in the BOM where two or more components reference each other. Incorrect BOM Structure: The BOM may have been incorrectly structured or maintained, leading to unintended relationships between components. Data Entry Errors: Manual data entry errors can lead to incorrect relationships being established between components.
    Solution: Review BOM Structure: Check the BOM structure for the components involved in the error message. Look for any circular references or unintended relationships. Correct Relationships: If you find a circular reference, you will need to
