What causes this issue?

The program uses an existing class as a template for the data container
to be generated. In some lines of source code the keywords are replaced
by input parameters.
A line of source code generated in this way is too long (> 72).
Experience shows that a long class name leads to this error. You should
choose a shorter name and start the generation process again.

• What is the cause and solution for SAP error message APPLG759 - DCW: Line of source code is too long; choose shorter name and regenerate ?

  The SAP error message APPLG759 indicates that a line of source code in your ABAP program exceeds the maximum allowed length. In ABAP, the maximum length for a line of code is typically 72 characters for standard ABAP statements, and 255 characters for certain constructs like string literals. This error often occurs when you have long variable names, comments, or concatenated strings that exceed these limits.
  Cause:
  
  Long Variable Names: If you are using excessively long names for variables, structures, or fields, it can lead to this error.
  Long Comments: Comments that are too lengthy can also contribute to exceeding the line length.

  Solution:
  
  Shorten Variable Names: Use shorter, more concise names for your variables and structures.
  Break Long Lines: If you have long lines of code, consider breaking them into multiple lines. You can use the & operator to concatenate strings across multiple lines.
  Refactor Code: Look for opportunities to refactor your code to reduce complexity and line length.
