Maybe you can add some more details. E.g. what kind of service you are implementing (odata, xsjs, ...) and why you chose that type. It would be of interest too if you are using XS Classic or XS Advanced.

I used XS Advance, sorry to miss that

When i talk over functions i mean the basic GRUD services and i create Odata Service.So i was, or better still, confused =), why in a tutorial explained how to implement create function for a Odata service in the XSA. When i see that when i create a second Odata service i must do nothing and can used create,read,update,delete immediately ?

Maybe you can add the tuturials you are talking about.

By default XSOData services support CRUD operations out of the box.

In the tutorial you linked (above in the comments) an example is shown which overwrites the create operation by an exit. This is an optional way, in case you wanna do e.g. some additional stuff, like the creation of a unique ID out of a sequence like shown in the example. Another example would be that you can enable write operations for OData services which are based e.g. on a view (within the exit implementation you can "redirect" the insert/update/delete to the relevant table for instance).
