• What is the cause and solution for SAP error message NI053 - Function & not defined in "select block" mode ?

  The SAP error message NI053, which states "Function & not defined in 'select block' mode," typically occurs when there is an issue with the way a function module or method is being called within a SELECT block in ABAP (Advanced Business Application Programming). This error indicates that the function being referenced is not available or not defined in the context of the SELECT block.
  Cause:
  
  Function Not Defined: The function or method you are trying to call is not defined in the context of the SELECT statement. This can happen if the function is not available in the database context or if it is not a valid function for use in a SELECT statement.
  Incorrect Syntax: There may be a syntax error in the way the function is being called within the SELECT statement.
  Database Compatibility: The function might not be compatible with the database being used, especially if it is a database-specific function.
  Scope Issues: The function might not be accessible due to scope issues, such as being defined in a different program or package.
  
  Solution:
  
  Check Function Definition: Ensure that the function or method you are trying to call is correctly defined and available in the context of the SELECT statement. You can do this by checking the function module in transaction SE37 or SE80.
  Review Syntax: Verify the syntax of your SELECT statement and the function call. Make sure that you are using the correct syntax for calling functions within a SELECT statement.
  Use Valid Functions: Ensure that you are using functions that are valid in the context of a SELECT statement. Some functions may only be used in other contexts (e.g., in a loop or as part of a calculation).
  Check Database Compatibility: If you are using database-specific functions, ensure that they are supported by the database you are working with.
  Debugging: Use debugging tools to step through the code and identify where the error occurs. This can help you pinpoint the exact cause of the issue.
