• What is the cause and solution for SAP error message CM887 - An entry already exists - Termination in & ?

  The SAP error message CM887 ("An entry already exists - Termination in &") typically occurs when there is an attempt to create or modify an entry in the system that already exists. This can happen in various contexts, such as when dealing with master data, configuration settings, or transactional data.

  Incorrect Data Input: Sometimes, the data being inputted may not be unique or may violate the uniqueness constraints defined in the system.

  Modify Existing Entry: If the entry already exists and you need to make changes, consider modifying the existing entry instead of creating a new one.
  Data Validation: Implement data validation checks in your processes to prevent duplicate entries from being created.
  Review Configuration: If you suspect a configuration issue, review the relevant configuration settings in the system to ensure they are set up correctly to prevent duplicates.
