GB018 - Details

• The SAP error message GB018, which states "Boolean statement not complete," typically occurs in the context of using selection criteria in reports or queries where a Boolean expression is expected but is not fully formed. This can happen in various scenarios, such as when using selection screens, query definitions, or report parameters.
  
  Cause:
  
  Incomplete Boolean Expression: The error usually arises when a Boolean statement (like AND, OR) is not properly completed. For example, if you have a condition that requires both sides of an AND or OR operator but only one side is provided.
  Syntax Errors: There may be syntax errors in the query or report definition that lead to incomplete logical expressions.
  Missing Parameters: If a required parameter for a Boolean condition is missing, it can trigger this error.
  
  
  Solution:
  
  Check the Query/Report Definition: Review the selection criteria or the query definition where the error occurs. Ensure that all Boolean expressions are complete and correctly
