• What is the cause and solution for SAP error message LTR2_BASIS204 - Externally linked non-transparent tables are not supported for selection ?

  The SAP error message LTR2_BASIS204 indicates that there is an attempt to select data from an externally linked non-transparent table, which is not supported in the context of the operation being performed. This typically occurs in scenarios involving data extraction or reporting where the system is trying to access a table that is not designed for direct selection.
  Cause:
  
  Externally Linked Tables: The error arises when the system encounters a table that is linked to an external data source (like a database outside of SAP) and is not a transparent table. Transparent tables are those that have a one-to-one correspondence with the database table.
  Non-Transparent Tables: These tables may include pooled tables, cluster tables, or any other type of table that does not allow direct SQL-like selection.
  Data Extraction: This error often occurs during data extraction processes, such as when using SAP BW or other reporting tools that attempt to read data from these non-transparent tables.
  
  Solution:
  
  Check Table Type: Verify the type of the table you are trying to access. You can do this by checking the table definition in the Data Dictionary (transaction SE11).
  Use Transparent Tables: If possible, modify your query or data extraction logic to use transparent tables instead of non-transparent or externally linked tables.
  Data Replication: If you need to access data from an external source, consider replicating the data into a transparent table within SAP. This can be done using tools like SAP Data Services or other ETL processes.
  Modify Queries: If you are using ABAP code or SQL queries, ensure that you are not trying to select from non-transparent tables directly. Instead, use appropriate views or join with transparent tables.
  Consult Documentation: Review SAP documentation or consult with your SAP Basis or ABAP team for best practices on handling data extraction and reporting.
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that might provide additional context or solutions for this error. SAP Notes can often provide patches or workarounds.
  SAP Community: Engage with the SAP Community forums to see if others have encountered similar issues and what solutions they have found.
  Transaction Codes: Familiarize yourself with transaction codes like SE11 (Data Dictionary), SE80 (Object Navigator), and SE37 (Function Builder) to help diagnose and resolve issues related to table access.
  
  By following these steps, you should be able to address the LTR2_BASIS204 error and successfully work with the data you need.
