SFB521 - Details

• The SAP error message SFB521, which states "Constants that span lines are not allowed," typically occurs in ABAP programming when a string constant is defined across multiple lines without proper concatenation or continuation. This error is common when developers attempt to define long strings or text literals that exceed a single line.
  
  Cause:
  The primary cause of this error is the incorrect formatting of string literals in ABAP code. In ABAP, string constants must be defined on a single line unless they are properly concatenated or split using specific syntax.
  
  Solution:
  To resolve the SFB521 error, you can take the following steps:
  
  
  Single Line Definition: Ensure that your string constants are defined on a single line. For example:
  DATA(lv_string) = 'This is a single line string constant'.
  
  
  Concatenation: If you need to define a long string that exceeds the line length, you can concatenate multiple strings using the CONCATENATE statement:
  DATA(lv_string) TYPE string.
  CONCATENATE 'This is a long string
