• What is the cause and solution for SAP error message SY105 - Source code record buffer overflow ?

  The SAP error message SY105: Source code record buffer overflow typically occurs when the source code of a program exceeds the maximum allowable size for a single record in the SAP system. This can happen during the development of ABAP programs, especially when large amounts of code are involved or when there are extensive comments or long lines of code.
  Cause:
  
  Excessive Code Length: The primary cause of this error is that the source code for a program, function module, or method exceeds the maximum length that can be handled in a single buffer record.
  Long Lines: If a single line of code is too long, it can also contribute to this overflow.
  Large Comments: Extensive comments or documentation within the code can also lead to this issue.
  
  Solution:
  
  
  Break Down Code: Refactor the code to break it down into smaller, more manageable pieces. This can involve:
  
  Splitting large methods into smaller ones.
  Reducing the number of lines in a single method or function.
  Using modularization techniques such as function modules or classes.
  
  
  
  Shorten Lines: Ensure that no single line of code exceeds the maximum length allowed. This can be done by:
  
  Breaking long lines into multiple shorter lines.
  Using concatenation for long strings.
  
  
  
  Reduce Comments: While comments are important for code readability, excessive comments can lead to this error. Consider:
  
  Summarizing comments.
  Using external documentation for extensive explanations.
  
  
  
  Check for Unused Code: Remove any unused or commented-out code that may be contributing to the buffer overflow.
  
  
  Use Include Programs: If the code is part of a larger program, consider using include programs to separate sections of code, which can help manage the size of individual source code records.
