Dear Thyagoo, As per your question, you want to know the difference between SAP HR and Non-SAP HR. If you are inquiring about the working aspect, you should phrase it as, "What is the difference in the working of SAP HR and Non-SAP HR?"
There is no significant difference between working in Non-SAP HR manually or using any other software compared to working in the SAP HR module. The formats and processes are similar to what you have experienced in HR.
Feel free to reach out if you have any more questions.
Best regards,
Pankaj
