I want to create employee via web service. I'm using following advice to create employee. https://answers.sap.com/answers/12983391/view.html.

But there are some problems that I didn't succeed;

I want the web service to be triggered automatically but couldn't find how. However, I decided to performed this operation via the button. But it's not on desired place. System doesn't allow me to extend button configuration area(no 1). Is there any work around for this?
2) (No 2) button group works only if I create custom BO. Because I couldn't create an action on extended BO.

3) Anyway I've created custom Bo, defined an action and bind it to Employee object. But this time I couldn't find my extension fields because the web service managePersonnelHiringIn have only system fields of Employee BO.
