VCH_LL105 - Overview

• Message type: E = Error

• Message class: VCH_LL - Messages for package VCH_LL

• Message number: 105

• Message text: Procedure chain with mutual dependencies found in BOM &1 position &2

What causes this issue?

The bill of material with number &1<(>,<)> position &2 has multiple
object dependencies of the type procedure assigned. These procedures
have mutual dependencies; this means that a value that is calculated by
a procedure is used in a later procedure. Since SAP HANA variant
configuration processes all procedures in parallel, these
mutually-dependent procedure chains cannot be calculated correctly.

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 VCH_LL105 - Procedure chain with mutual dependencies found in BOM &1 position &2 ?

  The SAP error message VCH_LL105 indicates that there is a circular dependency in the Bill of Materials (BOM) for a specific material. This means that the BOM contains components that reference each other in a way that creates a loop, making it impossible for the system to resolve the dependencies.
  
  Cause:
  
  Circular Dependencies: The most common cause of this error is that one or more components in the BOM reference each other in a circular manner. For example, Component A may reference Component B, and Component B may reference Component A.
  Incorrect BOM Structure: The BOM may have been incorrectly structured or maintained, leading to unintended dependencies.
  Data Entry Errors: Manual errors during BOM creation or modification can lead to such dependencies.
  
  
  Solution:
  
  Review BOM Structure: Check the BOM for the material specified in the error message. Look for any components that reference each other in a circular manner.
  Identify Circular References: Use transaction codes like CS03
