What causes this issue?

You have entered a character sequence in the Formula Builder that
contains a line break between two apostrophes (<ZH>'</>).

How to fix this error?

In the Formula Builder, constants must not contain a line break.

• What is the cause and solution for SAP error message SFB521 - Constants that span lines are not allowed ?

  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 that ' 
              'spans multiple lines ' 
              'and is concatenated properly' 
              INTO lv_string.
  
  
  Using && Operator: In newer versions of ABAP, you can use the && operator to concatenate strings:
  DATA(lv_string) = 'This is a long string that ' &&
                    'spans multiple lines ' &&
                    'and is concatenated properly'.
  
  
  Text Symbols: If you are working with text that needs to be translated or is user-facing, consider using text symbols (transaction SE63) to manage long texts.
  
  
  Avoiding Line Breaks: Ensure that there are no unintended line breaks in your string definitions. Check for any accidental line breaks that may have been introduced during coding.
  
  
  Related Information:
  
  ABAP Documentation: Refer to the official SAP ABAP documentation for guidelines on string handling and formatting.
  SAP Community: Engage with the SAP Community forums for discussions and solutions related to ABAP programming errors.
  Debugging: Use the ABAP debugger to step through your code and identify where the error is occurring, which can help in understanding how to fix it.
  
  By following these guidelines, you should be able to resolve the SFB521 error and properly define your string constants in ABAP.
