Differences between Make to Stock and Make to Order in SAP PP

Hi experts,

I have used the option Make to Stock and now I need to use the option Make to Order, I know the definitions of when I have to use MTS and when I have to use MTO,  but I need to know what are exactly the changes in SAP PP

Can you tell me what are exactly the differences between Make to Stock and Make to Order?

1.- What are the changes in the settings (SPRO)?

2.- What are the changes in the Master Data?

3.- What are the changes in the process?

4.- What are the changes in the transactions that should be used?

5.- What other differences are there?

Best regards,

Arnulfo Cordero Pradel
