• What is the cause and solution for SAP error message OO635 - Error importing classes (source code > 72 characters) ?

  The SAP error message OO635 indicates that there is an issue with importing classes due to the source code exceeding the maximum allowed length of 72 characters per line. This is a common limitation in ABAP (Advanced Business Application Programming) when dealing with certain types of source code, particularly when importing or exporting classes or methods.
  Cause:
  The error occurs when the source code of a class or method contains lines that exceed the 72-character limit. This can happen if:
  
  The code is formatted in a way that long lines are created.
  There are comments or strings that are too long.
  The code is being imported from an external source that does not adhere to the ABAP line length restrictions.
  
  Solution:
  To resolve the OO635 error, you can take the following steps:
  
  
  Check the Source Code: Review the source code of the class or method that is causing the error. Look for any lines that exceed 72 characters.
  
  
  Break Long Lines: If you find any lines that are longer than 72 characters, break them into multiple lines. In ABAP, you can use the continuation character (&) to split long statements across multiple lines.
  Example:
  DATA(lv_long_string) = 'This is a very long string that exceeds the 72 character limit and needs to be split into multiple lines.'.
  Can be split as:
  DATA(lv_long_string) = 'This is a very long string that exceeds the 72 character limit ' &&
                          'and needs to be split into multiple lines.'.
  
  
  Check Comments and Documentation: Ensure that comments and documentation within the code do not exceed the character limit. If necessary, split long comments into multiple lines.
  
  
  Use ABAP Editor: If you are using the ABAP editor (SE38 or SE80), it will typically highlight lines that exceed the limit. Use this feature to identify problematic lines.
  
  
  Re-import the Class: After making the necessary changes, try to re-import the class or method again.
