• Message text: &: Repeated line access possible via operation NEXTR

What causes this issue?

You have used the operation NEXTR and have specified a number.
You have already addressed a line with this number. Calling
it again initiates an endless loop.

• What is the cause and solution for SAP error message 5P206 - &: Repeated line access possible via operation NEXTR ?

  The SAP error message 5P206 with the description "Repeated line access possible via operation NEXTR" typically occurs in the context of ABAP programming, particularly when dealing with internal tables and their processing. This error indicates that there is a potential issue with how the program is accessing lines in an internal table, specifically when using the NEXTR operation.
  Cause:
  The error arises when the program attempts to access the same line of an internal table multiple times in a way that is not allowed or could lead to unintended behavior. This can happen if:
  
  The program logic is incorrectly structured, leading to repeated access of the same line.
  The use of the NEXTR operation is not properly managed, causing the program to attempt to read the same line again without advancing the pointer correctly.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Review the Code Logic: Check the logic of your program to ensure that you are not unintentionally accessing the same line of the internal table multiple times. Make sure that the loop or processing structure is correctly set up to advance through the table.
  
  
  Use Proper Loop Constructs: If you are using a loop to process the internal table, ensure that you are using the correct loop constructs (e.g., LOOP AT ... ENDLOOP) and that you are not mixing different access methods (like READ TABLE and NEXTR) in a way that could cause confusion.
  
  
  Check for Nested Loops: If you have nested loops, ensure that the inner loop does not access the same line of the internal table that the outer loop is currently processing.
  
  
  Debugging: Use debugging tools to step through the code and observe how the internal table is being accessed. This can help identify where the repeated access is occurring.
  
  
  Documentation and Best Practices: Refer to SAP documentation and best practices for handling internal tables and their access methods. This can provide insights into proper usage and common pitfalls.
  
  
  Related Information:
  
  NEXTR Operation: The NEXTR operation is used to access the next line in an internal table. It is important to ensure that the pointer is correctly managed to avoid accessing the same line multiple times.
  Internal Tables: Understanding how internal tables work in ABAP, including their structure, access methods, and performance considerations, is crucial for effective programming.
  SAP Notes: Check SAP Notes for any specific patches or updates related to this error message, as there may be known issues or fixes provided by SAP.
  
  By following these steps and understanding the underlying cause of the error, you should be able to resolve the issue and prevent it from occurring in the future.
