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

SAP Error Message - Details

• 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 that you are not trying to perform operations that are not allowed for multi-value characteristics. If necessary, consider changing the characteristic to a single-value characteristic if it makes sense for your configuration.
  
  
  Adjust Configuration Logic: If you are using configuration logic (like dependencies or constraints), review them to ensure they are compatible with multi-value characteristics. You may need to adjust the logic to handle multi-value characteristics appropriately.
  
  
  Use Alternative Approaches: If you need to work with multi-value characteristics, consider using alternative methods to achieve your goal. For example, you might need to aggregate values or handle them in a way that does not violate the constraints of multi-value characteristics.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for more information on how to work with multi-value characteristics and the limitations that apply.
  
  
  Seek Support: If you are unable to resolve the issue, consider reaching out to SAP support or your internal SAP team for assistance. They may have additional insights or solutions based on your specific configuration and use case.
  
  
  Related Information:
  
  SAP Variant Configuration (VC): Understanding how variant configuration works in SAP can help you better manage characteristics and their values.
  Characteristics and Values: Familiarize yourself with the differences between single-value and multi-value characteristics, and the implications of each in your configuration.
  SAP Notes and Knowledge Base Articles: Check for any relevant SAP Notes or articles that may address this specific error or provide additional context.
  
  By following these steps, you should be able to identify the root cause of the error and implement a suitable solution.
