  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  W8351 Expression 2 ('&2') cannot be multiline for operator '&1'
  
  Cause:
  This warning occurs when you use an operator in an ABAP expression where the second operand (Expression 2) is expected to be a single-line expression, but the provided expression spans multiple lines.
  In ABAP, certain operators require their operands to be single-line expressions. If you try to use a multiline expression (for example, a complex expression with line breaks or a block of code) as the second operand, the system raises this warning.
  Example scenario:
  DATA: result TYPE i.
  
  result = value1 + 
           ( value2
             + value3 ).  " Multiline expression used as second operand
  If the operator + expects a single-line expression for the second operand, but you provide a multiline expression, the warning W8351 is triggered.
  
  Solution:
  
  
  Make the second expression a single-line expression:
  
  Rewrite the expression so that the second operand is on a single line.
  
  
  Use intermediate variables:
  
  If the expression is complex, calculate it separately and assign it to a variable, then use that variable as the operand.
  
  
  Example fix:
  DATA: intermediate TYPE i,
        result TYPE i.
  
  intermediate = value2 + value3.
  result = value1 + intermediate.
  This way, the operator + receives a single-line expression as its second operand.
  
  Related Information:
  
  This warning is related to the syntax rules of ABAP expressions and operators.
  Operators like +, -, *, /, AND, OR, etc., expect their operands to be single-line expressions.
  Multiline expressions can be used in other contexts, but not directly as operands for these operators.
  The warning W8351 is a warning, not an error, so the program can still run, but it is recommended to fix it for clarity and to avoid unexpected behavior.
  Check the ABAP documentation on expressions and operators for more details on syntax rules.
