STO Configuration SLoc to SLoc

Dear MM experts,

I have configured STO configuration Sloc to sloc.

I did following configuration:

1.Define shipping data for Plant(Receiving plant)

2.Assign Delivery type and Checking rule @ Plant level(Issuing Plant)

3.Activate Stock Transfer Between Storage Locations

4.Assign Delivery Type and Checking Rule According to Storage Location(Issuing Storage location)
5.Define Shipping Data for Stock Transfers Between Storage Locations(confused whether it is for Issuing SLoc or for receiving SLoc)

6.Set Up Storage-Location-Dependent Shipping Point Determination

7.Necessary initial configuration like Customer master created,NN schedule line,NLN item catergories,NL del type is done.

While testing the configuration I am bit confused as far as "Define Shipping Data for Stock Transfers Between Storage Locations" is for receiving sloc or for supplying sloc and also not sure 'Define shipping data for Plant' is for receiving plant.

Refered document for STO config:

Kindly clear my query.
