• What is the cause and solution for SAP error message LQ605 - The explicit object reference can cause significantly longer runtimes ?

  The SAP error message LQ605 indicates that there is an explicit object reference in your ABAP code that can lead to significantly longer runtimes. This typically occurs when you are using explicit references to objects in a way that is not optimal for performance.
  Cause:
  The primary cause of this error is the use of explicit object references in your ABAP code, which can lead to inefficient memory usage and longer processing times. This often happens when:
  
  You are using SELECT statements that retrieve large datasets without proper filtering.
  You are not using internal tables or data structures efficiently.
  You are performing operations in a loop that could be optimized by using more efficient data access methods.
  
  Solution:
  To resolve the LQ605 error, consider the following solutions:
  
  
  Optimize Data Access:
  
  Review your SELECT statements to ensure they are retrieving only the necessary fields and records. Use WHERE clauses to filter data as much as possible.
  If you are using loops to process data, consider using FOR expressions or other methods that can reduce the number of iterations.
  
  
  
  Use Internal Tables Efficiently:
  
  Instead of using explicit object references, leverage internal tables to store and process data in bulk. This can significantly reduce the number of database accesses and improve performance.
  Use SORT and DELETE ADJACENT DUPLICATES on internal tables to minimize the data processed.
  
  
  
  Avoid Nested Loops:
  
  If your code contains nested loops, try to flatten them or use more efficient data access patterns. Nested loops can lead to exponential growth in processing time.
  
  
  
  Use Buffering:
  
  If applicable, consider using table buffering to reduce database access times. This can be particularly useful for tables that do not change frequently.
  
  
  
  Analyze Performance:
  
  Use transaction codes like SE30 (Runtime Analysis) or ST05 (SQL Trace) to analyze the performance of your code and identify bottlenecks.
  
  
  
  Code Review:
  
  Conduct a code review with peers or use static code analysis tools to identify potential performance issues in your ABAP code.
  
  
  
  Related Information:
  
  ABAP Performance Tuning: Familiarize yourself with best practices for writing efficient ABAP code. SAP provides guidelines and documentation on performance tuning.
  SAP Notes: Check for any relevant SAP Notes that may address specific issues related to the LQ605 error or provide additional optimization techniques.
  SAP Community: Engage with the SAP Community forums to seek advice from other developers who may have encountered similar issues.
  
  By addressing the explicit object references and optimizing your code, you should be able to resolve the LQ605 error and improve the performance of your SAP application.
