• What is the cause and solution for SAP error message TW108 - WHERE clause is too complicated to delete (line &) ?

  The SAP error message TW108, which states "WHERE clause is too complicated to delete (line &)," typically occurs in the context of ABAP programming, particularly when dealing with database operations that involve complex WHERE clauses in SQL statements. This error indicates that the WHERE clause in your SQL statement is too complex for the system to handle, particularly when trying to delete records.
  Cause:
  
  Complex WHERE Clause: The WHERE clause may contain too many conditions, subqueries, or joins that exceed the limits set by the database or the ABAP runtime environment.
  Performance Issues: The complexity of the WHERE clause can lead to performance issues, making it difficult for the database to optimize the query for deletion.
  Database Limitations: Different databases have different limitations on the complexity of SQL statements, and this error may arise if those limits are exceeded.
  
  Solution:
  
  Simplify the WHERE Clause: Review the WHERE clause and try to simplify it. Break down complex conditions into simpler ones or reduce the number of conditions.
  Use Temporary Tables: If the WHERE clause is inherently complex, consider using temporary tables to store intermediate results and then perform the delete operation on those results.
  Batch Processing: If you are trying to delete a large number of records, consider processing them in smaller batches rather than attempting to delete them all at once.
  Check for Unnecessary Joins: Ensure that you are not including unnecessary joins or subqueries in your WHERE clause that can be avoided.
  Review Database Documentation: Check the documentation for your specific database to understand its limitations regarding SQL complexity.
  
  Related Information:
