• What is the cause and solution for SAP error message 37190 - Select loop end below first loop block ?

  The SAP error message 37190, "Select loop end below first loop block," typically occurs in ABAP programming when there is a mismatch in the structure of a loop statement. This error indicates that the ENDLOOP statement is placed incorrectly in relation to the LOOP statement, specifically that the ENDLOOP is not properly closing the corresponding LOOP block.
  Cause:
  
  Incorrect Loop Structure: The ENDLOOP statement is placed before the corresponding LOOP statement, or there is a missing LOOP statement.
  Nested Loops: If you have nested loops, the ENDLOOP for an inner loop might be incorrectly placed, leading to confusion in the structure.
  Code Blocks: The error can also arise if there are conditional statements (like IF, CASE, etc.) that are not properly closed before the ENDLOOP.
  
  Solution:
  
  
  Check Loop Structure: Ensure that every LOOP statement has a corresponding ENDLOOP statement. The ENDLOOP should be placed after all the statements that are part of the loop.
  Example:
  LOOP AT itab INTO wa.
    " Your processing logic here
  ENDLOOP.
  
  
  Review Nested Loops: If you are using nested loops, make sure that each LOOP has its own ENDLOOP and that they are correctly nested.
  Example:
  LOOP AT itab1 INTO wa1.
    LOOP AT itab2 INTO wa2.
      " Your processing logic here
    ENDLOOP. " This ends the inner loop
  ENDLOOP. " This ends the outer loop
  
  
  Check Conditional Statements: Ensure that any conditional statements are properly closed before the ENDLOOP. If you have an IF statement inside a loop, make sure it has a corresponding ENDIF.
  Example:
  LOOP AT itab INTO wa.
    IF condition.
      " Your processing logic here
    ENDIF. " This ends the IF block
  ENDLOOP.
  
  
  Syntax Check: Use the ABAP editor's syntax check feature (usually F2 or the check button) to identify any syntax errors in your code.
  
  
  Code Review: If the error persists, review the surrounding code for any other structural issues that might be affecting the loop.
  
  
  Related Information:
  
  ABAP Documentation: Refer to the official SAP ABAP documentation for more details on loop structures and syntax.
  Debugging Tools: Utilize debugging tools in the ABAP Workbench to step through your code and identify where the loop structure is breaking down.
  Community Forums: If you are unable to resolve the issue, consider reaching out to SAP community forums or support for additional assistance.
  
  By following these steps, you should be able to resolve the error message 37190 and ensure that your loop structures are correctly implemented in your ABAP code.
