• What is the cause and solution for SAP error message FDT_QUERY009 - For all entries selection is not allowed with include memory ?

  The SAP error message FDT_QUERY009 indicates that there is an issue with the use of "For All Entries" (FAE) in a query when the query is using an internal table (or include memory) that is not suitable for this operation. This error typically arises in the context of ABAP programming, particularly when working with database queries.
  Cause:
  The error occurs because the "For All Entries" clause cannot be used with an internal table that is defined as an include memory table. This is a limitation in SAP's ABAP programming model. The "For All Entries" clause is designed to optimize database access by allowing you to retrieve records that match a set of keys from a database table, but it requires a standard internal table that is not defined as an include memory table.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Internal Table Definition: Ensure that the internal table you are using with the "For All Entries" clause is not defined as an include memory table. You can do this by checking the declaration of the internal table in your ABAP code.
  
  
  Use Standard Internal Tables: If you are currently using an include memory table, consider switching to a standard internal table. You can declare a standard internal table using the following syntax:
  DATA: lt_table TYPE TABLE OF your_table_type.
  
  
  Avoid Using FAE: If it is not feasible to change the internal table type, consider restructuring your query to avoid using "For All Entries". You can use a different approach, such as looping through the internal table and executing individual SELECT statements, although this may not be as efficient.
  
  
  Check for Empty Internal Table: Ensure that the internal table you are using with "For All Entries" is not empty. If it is empty, the query will not return any results, and you may want to handle this case explicitly in your code.
  
  
  Review Query Logic: Review the logic of your query to ensure that it aligns with best practices for performance and efficiency. Sometimes, restructuring the query can lead to better performance without the need for "For All Entries".
  
  
  Related Information:
  
  For All Entries (FAE): This is an ABAP SQL optimization technique that allows you to select records from a database table based on a set of keys stored in an internal table. It is important to ensure that the internal table is populated and not empty before using it in a query.
  Internal Tables in ABAP: Understanding the different types of internal tables in ABAP (standard, sorted, hashed, and include memory) is crucial for effective programming and avoiding errors like FDT_QUERY009.
  Performance Considerations: Using "For All Entries" can improve performance by reducing the number of database accesses, but it should be used judiciously and with the correct internal table types.
  
  By following these steps and understanding the underlying concepts, you should be able to resolve the FDT_QUERY009 error in your SAP environment.
