How To Fix WGDS_ENH126 - Characteristic values and generic material descriptions contain errors

SAP Error Message - Details

• Message type: E = Error

• Message class: WGDS_ENH -

• Message number: 126

• Message text: Characteristic values and generic material descriptions contain errors

What causes this issue?

The characteristic values for the new variants, and the descriptions for
the new generic article are not entered properly. The following error
situations are possible:
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. This prerequisite may not be fulfilled for some of the
new variants.
If there are several characteristic value columns, all columns need to
have a characteristic value assigned<(>,<)> to have a valid
characteristic value combination for the related variant. As long as
only some columns contain a characteristic value, the entered data is
invalid.
The languages used for the descriptions of the new generic article are
not unique.
Both the language and the description (line of text) have to be entered
to obtain a valid description line for the generic article. As long as
only one of these fields is filled, the entered data is invalid.
No description has been specified for the new generic article.

System Response

The lines with characteristic value errors and language or description
errors are indicated.

How to fix this error?

For the new variants, check the indicated lines for unique and complete
usage of characteristic values and characteristic value combinations.
For the descriptions of the new generic article, check the indicated
lines for unique usage of languages and complete description settings,
or delete the inconsistent line.

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_ENH126 - Characteristic values and generic material descriptions contain errors ?

  Certainly! Here's a detailed explanation for the SAP error message WGDS_ENH126: Characteristic values and generic material descriptions contain errors:
  
  Error Message
  WGDS_ENH126: Characteristic values and generic material descriptions contain errors
  
  Cause
  This error typically occurs in the context of SAP Variant Configuration (LO-VC) or Classification System when:
  
  The characteristic values assigned to a material or a generic material description are invalid, inconsistent, or do not conform to the expected format or domain.
  There are incorrect or missing characteristic values in the material master or in the generic material description.
  The characteristic values might be outside the allowed range, not assigned to the characteristic, or not maintained properly in the classification system.
  The generic material description (used for variant configuration or classification) contains invalid characteristic assignments or incomplete data.
  Sometimes, this error can also arise if the characteristic values are not maintained in the classification system or if there is a mismatch between the characteristic and its values.
  
  
  Solution
  To resolve the error WGDS_ENH126, follow these steps:
  
  
  Check Characteristic Values:
  
  Go to transaction CL02 (Change Characteristic) or CL03 (Display Characteristic).
  Verify that the characteristic values assigned to the material or generic material description are valid and exist in the system.
  Ensure that the characteristic values are correctly maintained and assigned to the characteristic.
  
  
  
  Check Material Classification:
  
  Use transaction MM02 (Change Material) and navigate to the Classification tab.
  Verify that the characteristic values assigned to the material are correct and consistent.
  Remove or correct any invalid characteristic values.
  
  
  
  Check Generic Material Description:
  
  If using generic material descriptions (e.g., in variant configuration), verify that the generic material description is correctly maintained.
  Use transaction MMGD or relevant variant configuration transactions to check the generic material description.
  Ensure that all characteristic values assigned are valid and consistent.
  
  
  
  Check Domain and Data Types:
  
  Verify that the characteristic values conform to the domain restrictions (e.g., length, data type).
  Use transaction SE11 to check the domain of the characteristic values.
  
  
  
  Rebuild or Update Classification Data:
  
  Sometimes, inconsistencies in classification data can cause this error.
  Use transaction CL20N (Change Class) or CL30N (Display Class) to verify and update the class data.
  Reassign or correct characteristic values if necessary.
  
  
  
  Check Variant Configuration Setup:
  
  If the error occurs during variant configuration, check the configuration profile and dependencies.
  Use transaction CU50 or CU51 to check configuration profiles and characteristic assignments.
  
  
  
  Run Consistency Checks:
  
  SAP provides consistency check reports for classification and variant configuration.
  Run reports like RCLSTCHK (Classification Consistency Check) to identify and fix inconsistencies.
