• What is the cause and solution for SAP error message FDT_EXPRESSIONS505 - Unexpected linefeed in constant string ?

  The SAP error message FDT_EXPRESSIONS505: Unexpected linefeed in constant string typically occurs in the context of SAP's Field Data Tool (FDT) or when working with expressions in ABAP (Advanced Business Application Programming). This error indicates that there is an unexpected line break or newline character in a string constant, which is not allowed in the syntax of the expression.
  Cause:
  The primary cause of this error is the presence of a linefeed (newline) character within a string constant. In programming, string constants should be defined in a single line without any breaks. If a linefeed is inadvertently included, the parser will not be able to interpret the string correctly, leading to this error.
  Solution:
  To resolve the FDT_EXPRESSIONS505 error, follow these steps:
  
  
  Check the Expression: Review the expression or string constant where the error is reported. Look for any line breaks or newline characters within the string.
  
  
  Remove Linefeeds: If you find any linefeeds, remove them. Ensure that the entire string is contained within a single line.
  
  
  Use Concatenation: If the string is too long and needs to be split for readability, consider using string concatenation. For example:
  DATA(lv_long_string) = 'This is a long string that ' &&
                         'is split across multiple lines.'.
  
  
  Use Proper Syntax: Ensure that the syntax used for defining strings is correct. For example, in ABAP, strings can be defined using single quotes (') or double quotes ("), but they should not span multiple lines unless concatenated.
  
  
  Test the Changes: After making the necessary adjustments, test the expression again to ensure that the error is resolved.
