How To Fix WGDS_ENH118 - Characteristic values are not used uniquely

SAP Error Message - Details

• Message type: E = Error

• Message class: WGDS_ENH -

• Message number: 118

• Message text: Characteristic values are not used uniquely

What causes this issue?

Each variant must have a unique characteristic value (one-dimensional
generic articles) or a unique characteristic value combination
(multi-dimensional generic articles) for the variant-creating
characteristics. Currently this prerequisite is not fulfilled for some
of the new variants.

System Response

The lines with non-unique characteristic value usage are indicated.

How to fix this error?

Check the indicated lines for unique usage of characteristic values and
characteristic value combinations.

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 WGDS_ENH118 - Characteristic values are not used uniquely ?

  SAP Error Message:
  
  WGDS_ENH118: Characteristic values are not used uniquely
  
  Cause:
  This error occurs in SAP when characteristic values assigned to a classification or configuration object are not unique. In other words, the system detects duplicate characteristic values where uniqueness is expected. This typically happens in the context of variant configuration, classification, or when maintaining characteristics and their values in the system.
  For example, if two or more characteristic values have the same identifier or description in a context where each value must be unique, the system throws this error.
  
  When does it occur?
  
  During creation or change of characteristics or characteristic values.
  When assigning characteristic values to classes or configurable materials.
  While saving configuration profiles or variant tables.
  During data migration or upload of characteristic values.
  In classification or variant configuration scenarios where uniqueness constraints are enforced.
  
  
  Solution:
  
  
  Check for Duplicate Characteristic Values:
  
  Go to transaction CT04 (Maintain Characteristics).
  Select the characteristic in question.
  Review the list of characteristic values.
  Identify any duplicate values (same value ID or description).
  
  
  
  Remove or Correct Duplicates:
  
  Delete or rename duplicate characteristic values to ensure each value is unique.
  If duplicates are intentional but must be distinguished, assign unique identifiers or descriptions.
  
  
  
  Check Classification Assignments:
  
  Use transaction CL20N or CL30N to review the classification data.
  Ensure that characteristic values assigned to objects are unique and consistent.
  
  
  
  Check Variant Configuration:
  
  In case of variant configuration, check the variant tables or dependencies for duplicate entries.
  Use transaction CU50 or CU51 to analyze variant tables and ensure uniqueness.
  
  
  
  Data Upload / Migration:
  
  If the error occurs during data upload, verify the source data for duplicates.
  Cleanse the data before upload.
  
  
  
  Use SAP Notes / Support:
  
  Check SAP Notes for any known issues related to WGDS_ENH118.
  Sometimes, patches or support packages address related bugs.

  SAP Notes:
  
  Search for notes related to WGDS_ENH118 or characteristic value uniqueness issues.
  
  
  
  Additional Tips:
  
  Always backup data before deleting or modifying characteristic values.
  Use consistent naming conventions to avoid confusion.
  Validate data integrity after changes.
  
  
  
  
  Summary:
  The error WGDS_ENH118 indicates that characteristic values are not unique where they must be. The solution involves identifying and removing or correcting duplicate characteristic values in the system, especially in classification and variant configuration contexts. Proper data maintenance and validation prevent this error.
