• What is the cause and solution for SAP error message LTR2_BASIS205 - Child tables of non-transparent tables are not supported for selection ?

  The SAP error message LTR2_BASIS205 indicates that there is an attempt to select data from child tables of non-transparent tables, 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 data from a non-transparent table's child tables.
  Cause:
  
  Non-Transparent Tables: Non-transparent tables in SAP are database tables that do not have a one-to-one mapping with a database table. They are often used for complex data structures, such as pooled or cluster tables.
  Child Tables: These are tables that are related to a parent table in a hierarchical structure. In the case of non-transparent tables, the child tables cannot be accessed directly for selection operations.
  Data Extraction: The error often arises during data extraction processes, such as when using SAP Data Services, SAP BW, or other reporting tools that attempt to read from these non-transparent structures.
  
  Solution:
  
  Use Transparent Tables: If possible, modify your data extraction or reporting logic to use transparent tables instead of non-transparent tables. Transparent tables are fully supported for selection operations.
  Join Logic: If you need to access data from non-transparent tables, consider using join logic in your ABAP code or data extraction process to retrieve the necessary data from the parent table instead.
  Data Modeling: In cases where you need to work with non-transparent tables, consider creating a view or a new transparent table that consolidates the necessary data from the non-transparent structure.
  Check Data Source: Ensure that the data source you are using for extraction or reporting is correctly configured and does not attempt to access child tables of non-transparent tables.
  
  Related Information:
  
  SAP Documentation: Refer to the official SAP documentation for more details on table types and their characteristics.
  ABAP Development: If you are developing custom reports or data extraction programs, familiarize yourself with the differences between transparent and non-transparent tables in ABAP.
  SAP Community: Engage with the SAP Community forums for insights and solutions from other users who may have encountered similar issues.
  
  By addressing the underlying cause of the error and implementing the suggested solutions, you should be able to resolve the issue and successfully perform your data selection operations.
