How To Fix PPECMP603 - Relationship of node &1 to node &2 creates recursion via bill of material

PPECMP603 - Overview

• Message type: E = Error

• Message class: PPECMP - Messages for iPPE CMP Application (Components)

• Message number: 603

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

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.

• What is the cause and solution for SAP error message PPECMP603 - Relationship of node &1 to node &2 creates recursion via bill of material ?

  The SAP error message PPECMP603 indicates that there is a recursion issue in the bill of materials (BOM) structure. 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
