• What is the cause and solution for SAP error message W8350 - Expression 1 ('&2') must be multiline for operator '&1' ?

  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  W8350 Expression 1 ('&2') must be multiline for operator '&1'
  
  Cause:
  This warning message occurs in the SAP Query or SAP Logical Database (LDB) environment when you are defining a selection condition or a logical expression involving operators that require the first expression to be multiline (i.e., a list or range of values), but the expression provided is a single-line or single-value expression.
  Specifically, the message means that the operator you are using (e.g., IN, NOT IN, BETWEEN, or other set-based operators) expects the first operand (Expression 1) to be a multiline expression (a list or table of values), but the expression you provided is a single value or single-line expression.
  
  Explanation:
  
  Expression 1 ('&2'): The first operand in your condition.
  Operator ('&1'): The operator you are using that requires Expression 1 to be multiline.
  
  For example, if you use an operator like IN or NOT IN, the left-hand side should be a list or range of values, not a single value.
  
  Typical Scenario:
  You might have a condition like:
  field IN 'value'
  But IN expects a list of values, like:
  field IN ('value1', 'value2', 'value3')
  Or in SAP Query, you might be trying to compare a single value with a set of values incorrectly.
  
  Solution:
  
  Check the operator used: Verify if the operator you are using requires a multiline expression (list or range).
  Adjust Expression 1: Make sure that Expression 1 is a multiline expression (e.g., a list of values, a range, or a table).
  Modify the condition: If you want to compare a single value, use an operator suitable for single values (e.g., =, <>, <, >).
  Use correct syntax: For operators like IN, provide a list of values or a table expression.
  
  
  Example Fix:
  If your condition is:
  field IN 'ABC'
  Change it to:
  field = 'ABC'
  Or if you want to check multiple values:
  field IN ('ABC', 'DEF', 'GHI')
  
  Related Information:
  
  This message is a warning (W), not an error, so the system allows you to proceed but indicates a potential logical issue.
  It often appears in SAP Query, Logical Database (LDB), or ABAP programs where dynamic conditions are built.
  Review the operator documentation to understand which operators require multiline expressions.
  Check the SAP Note or SAP Help Portal for more details on query conditions and operators.
