Hi Jen,
All the methods mentioned by you are used for replicating data
To replicate data from ECC you can either use SLt, DXC or SAP Data Services
For SLT you require LT Server to replicate data
For DXC, you need to implement few SAP Notes in your ECC system.
For Data Services, you need Data Services tool
The scenario you mentioned above is used to replicate tables using SLT, but before using this Provisioning tab in HANA, you need to configure SLT and create connection between ECC and HANA.. after configuration only you will be able to get tables
For using SLT you can check this video

You can also check my blog to get all documents related to each if these technologies and i recommend you to read them first.
