How To Fix VCH_L2A_CHECKS123 - Operations on multi-value characteristics is not supported

VCH_L2A_CHECKS123 - Overview

• Message type: E = Error

• Message class: VCH_L2A_CHECKS - VCH Transition AVC Check Messages

• Message number: 123

• Message text: Operations on multi-value characteristics is not supported

What causes this issue?

LO-VC uses a set-based semantics for multi-valued characteristics in
dependencies and a value-based semantics in constraints.
Advanced Variant Configuration uses set-based semantics in all object
dependencies, so arithmetic operations on multi-value characteristics in
constraints are not supported.

• What is the cause and solution for SAP error message VCH_L2A_CHECKS123 - Operations on multi-value characteristics is not supported ?

  The SAP error message VCH_L2A_CHECKS123 indicates that there is an issue with operations on multi-value characteristics in the context of SAP Variant Configuration (VC). This error typically arises when you are trying to perform an operation that is not supported for characteristics that can hold multiple values.
  
  Cause:
  
  
  Multi-Value Characteristics: The error occurs when you attempt to perform operations (like checks, assignments, or calculations) on characteristics that are defined to hold multiple values. In SAP VC, certain operations are restricted for multi-value characteristics because they can lead to ambiguity or conflicts in the configuration.
  
  
  Configuration Settings: The configuration settings for the product or variant may not be set up correctly, leading to attempts to manipulate multi-value characteristics in ways that are not allowed.
  
  
  Incompatible Operations: The operation you are trying to perform may not be compatible with the data model of the multi-value characteristic.
  
  
  
  Solution:
  
  
  Review Characteristic Settings: Check the settings of the characteristics involved. Ensure
