  The SAP error message COM_PME_PARSER018 indicates that there is a syntax issue in an expression where an operator is used without the necessary parentheses. This error typically occurs in the context of formula expressions, particularly in the SAP BusinessObjects or SAP BW environments, where complex calculations or expressions are defined.
  Cause:
  The error arises when an expression contains operators (like +, -, *, /, etc.) that require explicit grouping to clarify the order of operations. If parentheses are missing, the parser cannot correctly interpret the intended calculation, leading to this error message.
  Solution:
  To resolve this error, you need to review the expression that triggered the error and ensure that all necessary parentheses are included. Here are the steps to fix the issue:
  
  
  Identify the Expression: Locate the expression that is causing the error. This may be in a calculated field, a formula, or a query.
  
  
  Add Parentheses: Ensure that all operations are properly grouped with parentheses. For example:
  
  Instead of writing A + B * C, write (A + B) * C or A + (B * C) depending on the intended order of operations.
  
  
  
  Test the Expression: After modifying the expression, test it again to ensure that it no longer triggers the error.
  
  
  Review Documentation: If you are unsure about the correct syntax, refer to the SAP documentation or help resources for guidance on writing expressions.
  
  
  Related Information:
  
  Operator Precedence: Understanding operator precedence can help you determine where parentheses are needed. Operators like multiplication and division typically have higher precedence than addition and subtraction.
