[Scip] how to get the lower and upper bounds of each integer variable

Dear all,

At each node in the B&B tree, I want to get the lower and upper bounds for some integer variables. I checked the manual of SCIP and found two routines: 
SCIPvarGetLbGlobala( CIPvarGetUbGlobal )
and
SCIPvarGetLbLocal( SCIPvarGetUbLocal)

Should I use the local methods?  What is the different between global and local bounds?  Thanks.
