How to use bone tool without getting my vector/object distort?

Question

Wish to get some help here. I drawn my human body figure using pen tool. I connect the bone tool directly without separating the part of (hand,legs and head) into symbol. After that, I try to move the hand but it get distort. Not just the hand but the body and head also getting distort as well. Do we need to necessary convert the body parts to symbol first before connecting the bone? Thanks.

> So, is it right if I say that the services available in the backend are already implemented? And just creating an endpoint for them would make them ready for use?
Yes: kind of instant services 
> Also if I consume a service, say, 'CreateSalesOrder_In' for example, will it create entries in all my Sales order relevant tables (VBAK, VBAP) automatically using a BAPI internally?
The service has the task to do all necessary steps, whether with or without using a BAPI.
> Actually,  I have these doubts because during my time at SAP Labs (for the composites team in BusinesByDesign), I used to create business objects in the ESR and create an implementation for the same in the backend using BOPF. But now, in the customer scenario, where a full fledged ECC implementation is used, I am unaware as to how the services would update the tables or even read the relevant data.
My consumer view on aservice is that I do not have to know how the service works, just need to know how to call it.
