• What is the cause and solution for SAP error message RSPP110 - Key is not unique; cannot save ?

  The SAP error message RSPP110: Key is not unique; cannot save typically occurs in the context of SAP's data management or reporting tools, particularly when dealing with data records that are expected to be unique but are found to have duplicates. This error can arise in various scenarios, such as when trying to save a record in a database table or when working with data models in SAP BW (Business Warehouse) or SAP HANA.
  Cause:
  The error is caused by an attempt to save a record that violates the uniqueness constraint of a key field in the database. This can happen due to:
  
  Duplicate Entries: There are already existing records in the database that have the same key values as the record you are trying to save.
  Incorrect Data Entry: The data being entered may have been incorrectly populated, leading to duplicates.
  Data Model Issues: In data modeling scenarios, the design may not enforce uniqueness properly, or there may be issues with the data source.
  
  Solution:
  To resolve the RSPP110 error, you can take the following steps:
  
  
  Check for Duplicates:
  
  Query the database or the relevant data model to identify existing records that have the same key values as the one you are trying to save.
  Use transaction codes like SE16 or SE11 to view the table data and check for duplicates.
  
  
  
  Modify the Data:
  
  If duplicates are found, you may need to modify the data you are trying to save to ensure that it has a unique key.
  Alternatively, if the existing records are not needed, consider deleting or archiving them.
  
  
  
  Review Data Entry Processes:
  
  Ensure that the data entry processes are designed to prevent duplicates. This may involve implementing validation checks or using unique identifiers.
  
  
  
  Adjust Data Model:
  
  If you are working with a data model, review the design to ensure that uniqueness constraints are properly defined and enforced.
  
  
  
  Consult Documentation:
