• What is the cause and solution for SAP error message LMD_RTSL_CMP_MSGS020 - Key field combination is not unique. Contact the help desk. ?

  The SAP error message LMD_RTSL_CMP_MSGS020 indicates that there is a problem with the uniqueness of a key field combination in the system. This error typically arises in the context of logistics or supply chain management, particularly when dealing with master data or transactional data that requires unique identifiers.
  Cause:
  The error occurs when the system encounters a situation where it expects a unique combination of key fields (such as material number, plant, storage location, etc.), but finds multiple entries that match the criteria. This can happen due to:
  
  Data Duplication: There may be duplicate entries in the database for the key fields being processed.
  Incorrect Configuration: The configuration settings for the relevant data model may not enforce uniqueness correctly.
  Data Migration Issues: If data was migrated from another system, it may not have been cleaned properly, leading to duplicates.
  User Input Errors: Users may inadvertently create duplicate records through manual entry.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Identify Duplicates:
  
  Use transaction codes like SE16 or SE11 to check the relevant database tables for duplicate entries based on the key fields mentioned in the error message.
  You can also use SQL queries to find duplicates if you have access to the database.
  
  
  
  Data Cleanup:
  
  Once duplicates are identified, you will need to decide which records to keep and which to delete or merge. This may involve consulting with business stakeholders to ensure that important data is not lost.
  Use transaction codes like MM02 (Change Material) or similar to modify or delete the duplicate records.
  
  
  
  Check Configuration:
  
  Review the configuration settings in the relevant modules (like Material Management, Sales and Distribution, etc.) to ensure that uniqueness constraints are properly set up.
  If necessary, consult with your SAP Basis or functional team to adjust the settings.
  
  
  
  Data Validation:
  
  Implement validation checks in your data entry processes to prevent future duplicates from being created.
  Consider using SAP's built-in tools for data quality management.
  
  
  
  Contact Help Desk:
