How To Fix 37580 - Select end of loop block

SAP Error Message - Details

• Message type: E = Error

• Message class: 37 - Screen Painter

• Message number: 580

• Message text: Select end of loop block

What causes this issue?

You created a step loop. To do this, both the position and the size of
the loop block are defined as a rectangular section. One corner of the
loop block is already fixed by the field on which the cursor stands.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Place the cursor so that the opposite corner of the the loop block is
fixed and choose <LS>Select block end</>.
In most cases, loop blocks are defined as one-line loop blocks. The
rectangular section is thus special in that it is part of a line.
The system first generates a minimal step loop where the loop block is
repeated twice.
If you want more than two repetition blocks, place the cursor on the
desired last line of the step loop area and select <LS> Select loop
end</>.
Then, by pressing F3=Back, you can leave step loop processing and
return to the fullscreen.

  The SAP error message "37580: Select end of loop block" typically occurs in the context of ABAP programming when there is an issue with the structure of a loop or a SELECT statement in your code. This error indicates that the ABAP runtime environment has encountered a problem with the way the loop or block is defined, particularly when it expects an "ENDLOOP" statement but cannot find it.
  Cause:
  
  Missing ENDLOOP Statement: The most common cause is that there is a missing ENDLOOP statement for a corresponding LOOP statement in your code.
  Incorrect Nesting: If you have nested loops, ensure that each loop has its corresponding ENDLOOP statement.
  Syntax Errors: Other syntax errors in the code can also lead to this error, as the parser may misinterpret the structure of the code.
  Conditional Statements: If you have conditional statements (like IF, CASE, etc.) inside a loop, ensure that they are properly closed.
  
  Solution:
  
  Check for Missing ENDLOOP: Review your code to ensure that every LOOP statement has a corresponding ENDLOOP. 
  LOOP AT itab INTO wa.
    " Your processing logic here
  ENDLOOP.
  
  Verify Nesting: If you have nested loops, make sure that each loop is properly closed.
  LOOP AT itab1 INTO wa1.
    LOOP AT itab2 INTO wa2.
      " Your processing logic here
    ENDLOOP.
  ENDLOOP.
  
  Review Syntax: Check for any syntax errors that might be causing the parser to misinterpret the structure of your code.
  Use Syntax Check: Use the ABAP editor's syntax check feature (Ctrl + F2) to identify any syntax errors in your code.
  Debugging: If the error persists, consider using the debugger to step through your code and identify where the issue arises.
