• What is the cause and solution for SAP error message R7B665 - Characteristic &1 contains data. High cardinality change not possible ?

  The SAP error message R7B665 indicates that a characteristic in your data model has high cardinality, meaning it contains a large number of unique values. This situation can arise when you attempt to change the properties of a characteristic that is already populated with data, particularly when trying to change it to a high cardinality characteristic.
  
  Cause:
  
  High Cardinality: The characteristic in question has a large number of unique values, which makes it unsuitable for certain types of changes.
  Data Already Exists: The characteristic already contains data, and SAP does not allow changes that could potentially disrupt the integrity of the existing data.
  Modeling Restrictions: Certain changes to characteristics (like changing from low to high cardinality) are restricted in SAP BW/4HANA or SAP BW due to the potential impact on performance and data integrity.
  
  
  Solution:
  
  Review the Characteristic: Check the characteristic to understand its current usage and the number of unique values it contains.
