• What is the cause and solution for SAP error message 37073 - Selection in loop continuation lines is not allowed ?

  The SAP error message 37073, "Selection in loop continuation lines is not allowed," typically occurs in ABAP programming when there is an attempt to use a selection statement (like SELECT, SELECT-OPTIONS, or PARAMETERS) within a loop that is not allowed. This error is often related to the structure of the code and how the loops and selection statements are organized.
  Cause:
  
  Improper Placement of Selection Statements: The error usually arises when a selection statement is placed inside a loop that is not designed to handle it. For example, if you have a LOOP AT statement and you try to perform a SELECT query inside that loop, it can lead to this error.
  Nested Loops: If you have nested loops and the inner loop contains a selection statement, it may also trigger this error.
  Incorrect Use of Control Structures: Using control structures incorrectly can lead to this error, especially if the logic is not properly structured.
  
  Solution:
  
  
  Reorganize Your Code: Move the selection statement outside of the loop. Perform the selection before entering the loop, and then process the results within the loop.
  DATA: lt_data TYPE TABLE OF your_table_type.
  
  SELECT * FROM your_table INTO TABLE lt_data WHERE your_conditions.
  
  LOOP AT lt_data INTO DATA(ls_data).
      " Process each entry in lt_data
  ENDLOOP.
  
  
  Use Temporary Tables: If you need to filter or process data based on certain conditions, consider using temporary tables or internal tables to store the results of your selection before looping through them.
  
  
  Check Logic: Ensure that the logic of your program does not require a selection statement within a loop. If it does, consider restructuring your approach.
  
  
  Related Information:
  
  ABAP Documentation: Refer to the official SAP ABAP documentation for best practices on using loops and selection statements.
  Performance Considerations: Be mindful of performance implications when moving selection statements outside of loops, especially if the dataset is large. Fetching data in bulk before processing can often be more efficient.
  Debugging: Use the ABAP debugger to step through your code and identify where the error occurs. This can help you understand the flow of your program and where adjustments are needed.
  
  By following these guidelines, you should be able to resolve the error message 37073 and improve the structure of your ABAP code.
