KZ026 - Details

• The SAP error message KZ026 indicates that there is a discrepancy between the variance key assigned to a lower-level cost object and the variance key assigned to its higher-level cost object. This typically occurs in the context of controlling and cost accounting, particularly when dealing with cost centers, internal orders, or projects.
  
  Cause:
  
  Inconsistent Variance Keys: The lower-level cost object (e.g., a cost center or internal order) has a different variance key than its parent cost object. Variance keys are used to determine how variances are calculated and reported.
  
  Configuration Issues: There may be a configuration issue in the controlling area settings or in the assignment of variance keys to cost objects.
  Data Entry Errors: Manual entry errors during the creation or modification of cost objects can lead to mismatched variance keys.
