How To Fix 28406 - Restrictions of value set using dependencies not yet supported: &1

SAP Error Message - Details

• Message type: E = Error

• Message class: 28 - Configuration

• Message number: 406

• Message text: Restrictions of value set using dependencies not yet supported: &1

What causes this issue?

Inferences (restrictions) for restrictable characteristics are
currently only supported in connection with a table call.
Example:
If the two restrictable characteristics ?X and ?Y are entered in the
restriction ?X >= 2*?Y + 5, you cannot use the value set of ?Y to infer
a restriction for the value set of ?X, and you cannot use the value set
of ?X to infer a restriction for the value set of ?Y. This option is to
be made available in future.

System Response

Inference of restrictions to a value set that are not from a table call
cannot currently be processed and is marked as incorrect.

How to fix this error?

Only use single-value characteristics in such situations for now.

  The SAP error message 28406, which states "Restrictions of value set using dependencies not yet supported: &1," typically occurs in the context of SAP Variant Configuration (VC). This error indicates that there is an attempt to use a dependency to restrict a value set, but the system does not support this operation in the current context.
  Cause:
  
  Dependency Usage: The error arises when a dependency (like a constraint or a selection condition) is applied to a characteristic that is part of a value set, but the system does not support this type of restriction.
  Configuration Settings: The configuration settings or the way the characteristics and dependencies are defined may not be compatible with the intended use.
  Version Limitations: The version of SAP you are using may have limitations regarding the use of dependencies with value sets.
  
  Solution:
  
  Review Dependencies: Check the dependencies that are being used in your configuration. Ensure that they are correctly defined and that they do not attempt to restrict value sets in a way that is unsupported.
  Modify Configuration: If possible, modify the configuration to avoid using dependencies to restrict value sets. Instead, consider using other methods to achieve the desired configuration behavior.
  Check SAP Notes: Look for relevant SAP Notes or updates that may address this issue. Sometimes, SAP releases patches or notes that provide solutions or workarounds for specific error messages.
  Consult Documentation: Review the SAP documentation related to Variant Configuration and dependencies to ensure that you are using them correctly.
  Contact SAP Support: If the issue persists and you cannot find a resolution, consider reaching out to SAP Support for assistance. They may provide insights specific to your system configuration.
  
  Related Information:
  
  SAP Variant Configuration: Understanding how variant configuration works in SAP can help in troubleshooting issues related to dependencies and value sets.
  Dependencies in VC: Familiarize yourself with the types of dependencies (e.g., selection conditions, constraints) and how they interact with characteristics and value sets.
  SAP Community: Engaging with the SAP Community forums can provide additional insights and solutions from other users who may have encountered similar issues.
