How To Fix PPECMP601 - Material &1 in &2 creates recursion via bill of material

PPECMP601 - Overview

• Message type: E = Error

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

• Message number: 601

• Message text: Material &1 in &2 creates recursion via bill of material

What causes this issue?

Material &V1& of &V2& creates a recursion involving a bill of material.
The header material of this bill of material is &V3&, the component is
&V4&.
The entered material &V1& is part of a bill of material. If you add this
material to the product structure, 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 likewise has to be part of a bill of 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&, &V3&,
and &V4&). The original error can also lie with other materials of the
product structure that exist in bills of material.

Procedure for System Administrators

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

• What is the cause and solution for SAP error message PPECMP601 - Material &1 in &2 creates recursion via bill of material ?

  The SAP error message PPECMP601 indicates that there is a recursion issue in the bill of materials (BOM) for a specific material. This typically occurs when a material is defined in its own BOM, either directly or indirectly, leading to a circular reference. Here’s a breakdown of the cause, potential solutions, and related information:
  
  Cause:
  
  Direct Recursion: The material is listed in its own BOM. For example, if Material A includes itself in its BOM, it creates a direct recursion.
  Indirect Recursion: The material is part of another material's BOM, which in turn includes the original material. For instance, if Material A is in Material B's BOM, and Material B is in Material A's BOM, this creates an indirect recursion.
  Incorrect BOM Configuration: Errors in the BOM configuration or data entry can lead to unintended recursive relationships.
  
  
  Solution:
  
  
  Review BOM Structure:
  
  Go to the BOM for the material in question and check if it includes itself or
