CM_EHPRC_EXPLOSION023 - Data inconsistency encountered: recursive component (Spec &1)

SAP Error Message - Details

• Message type: E = Error

• Message class: CM_EHPRC_EXPLOSION - Messages used by BOS explosion function

• Message number: 023

• Message text: Data inconsistency encountered: recursive component (Spec &1)

What causes this issue?

The component based on specification &V1& is contained in its own
composition. This is inconsistent.

System Response

The product structure is not expanded beyond the second occurance of the
same component.

How to fix this error?

Change the composition of specification &V1& and remove the self
reference. Note that the inconsistency may occur over several levels of
the structure. Therefore, if &V1& is not a direct component of itself,
also check the lower levels of the structure of &V1&.

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 CM_EHPRC_EXPLOSION023 - Data inconsistency encountered: recursive component (Spec &1) ?

  The SAP error message CM_EHPRC_EXPLOSION023 indicates that there is a data inconsistency related to a recursive component in the context of a product structure or bill of materials (BOM). This error typically arises when the system detects a loop or recursion in the component structure, which can occur if a component references itself directly or indirectly.
  Cause:
  
  Recursive Component Definition: The most common cause of this error is that a component in the BOM or product structure is defined in such a way that it refers back to itself, either directly or through a chain of other components.
  Incorrect BOM Configuration: If the BOM is not configured correctly, it may lead to circular references.
  Data Integrity Issues: There may be issues with the data integrity in the database, leading to inconsistencies in how components are defined.
  
  Solution:
  
  Review BOM Structure: Check the BOM or product structure for any components that may be referencing themselves. Look for circular references and correct them.
  Use the BOM Transaction: Use transaction codes like CS03 (Display BOM) or CS02 (Change BOM) to analyze the structure and identify any recursive components.
  Check Component Definitions: Ensure that all components are defined correctly and do not point back to themselves.
  Data Consistency Check: Run a consistency check on the BOM using transaction CSBI (BOM Information System) or similar tools to identify and resolve inconsistencies.
  Consult Documentation: Refer to SAP documentation or notes related to BOM management and recursive components for additional guidance.
  SAP Support: If the issue persists, consider reaching out to SAP support for assistance, especially if it appears to be a bug or a deeper data integrity issue.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as CS01 (Create BOM), CS02 (Change BOM), CS03 (Display BOM), and CS11 (Display BOM Level).
  SAP Notes: Check for any SAP Notes that may address this specific error or provide additional troubleshooting steps.
  BOM Structure: Understand the structure of BOMs in SAP and how components are linked to avoid creating recursive definitions in the future.
  
  By following these steps, you should be able to identify and resolve the issue causing the CM_EHPRC_EXPLOSION023 error in SAP.
