How To Fix PPECMP602 - Material &1 in &2 creates recursion via follow-up material in BOM

PPECMP602 - Overview

• Message type: E = Error

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

• Message number: 602

• Message text: Material &1 in &2 creates recursion via follow-up material in BOM

What causes this issue?

Material &V1& of &V2& creates a recursion involving a follow-up material
of a bill of material component.
The header material of this bill of material is &V1&, the component is
&V3&, the follow-up material is &V4&.
The entered material &V1& is part of a bill of material. If you add this
material to the product structure in &V2&, the product structure becomes
recursive, as follows:
Either directly by an immediately-assigned other node and its material
reference or by a different material in the bill of material
Or indirectly by a different material that exists in the product
structure and which likewise has to be part of a bill of material
In the present case, the recursion is caused by a follow-up material.

System Response

The entered value (material nummer &V1&) is not saved in the changed
structure object.

How to fix this error?

Start the recursivity analysis with the specified materials (&V1& and
&V4&). Note when doing so that the recursion is caused by a follow-up
material (&V4&). The original error can also lie with other materials in
the product structure that exist in bills of material and have follow-up
materials.

• What is the cause and solution for SAP error message PPECMP602 - Material &1 in &2 creates recursion via follow-up material in BOM ?

  The SAP error message PPECMP602 indicates that there is a recursion issue in the Bill of Materials (BOM) for a material. Specifically, it means that the material you are trying to process (denoted as &1) is creating a recursive relationship through a follow-up material (denoted as &2). This typically occurs when a material is defined in such a way that it references itself, either directly or indirectly, through its BOM structure.
  
  Cause:
  
  Recursive BOM Structure: The most common cause of this error is that the BOM for the material includes a follow-up material that eventually leads back to the original material, creating a loop.
  Incorrect BOM Configuration: There may be an incorrect configuration in the BOM where materials are not properly defined, leading to unintended recursive relationships.
  Data Entry Errors: Manual errors during BOM creation or modification can lead to incorrect references.
  
  
  Solution:
  
  Review the BOM: Check the BOM for the material in question. Look for
