• What is the cause and solution for SAP error message OO810 - Do not use spaces in the reference type ?

  The SAP error message OO810, which states "Do not use spaces in the reference type," typically occurs when you are trying to create or modify an object in the Object-Oriented (OO) programming environment of SAP ABAP, and the reference type you are using contains spaces. This can happen in various contexts, such as when defining classes, interfaces, or data types.
  Cause:
  The primary cause of this error is the presence of spaces in the reference type name. In SAP ABAP, reference types (like class names, interface names, etc.) must adhere to specific naming conventions, which do not allow spaces. Spaces can lead to ambiguity and confusion in the code, which is why the system enforces this rule.
  Solution:
  To resolve the OO810 error, you should:
  
  
  Check the Reference Type Name: Review the reference type you are trying to use and ensure that it does not contain any spaces. This includes checking for leading or trailing spaces as well.
  
  
  Rename the Reference Type: If you find that the reference type name does contain spaces, rename it to a valid name that adheres to SAP's naming conventions. Valid names typically consist of alphanumeric characters and underscores, without any spaces.
  
  
  Update References: After renaming the reference type, ensure that all references to this type in your code are updated accordingly to avoid further errors.
  
  
  Test the Changes: After making the necessary changes, test your program or object to ensure that the error is resolved and that everything functions as expected.
  
  
  Related Information:
  
  Naming Conventions: Familiarize yourself with SAP's naming conventions for classes, interfaces, and other objects. This will help you avoid similar issues in the future.
  Documentation: Refer to the official SAP documentation for more details on object-oriented programming in ABAP, which includes guidelines on naming and structuring your code.
  Debugging: If you continue to encounter issues, consider using the ABAP debugger to trace where the error is occurring and to inspect the values of variables and types at runtime.
  
  By following these steps, you should be able to resolve the OO810 error and continue with your development work in SAP.
