Value Mapping or Lookup Table

Hi,

There is a requirement that we would need to dump a table data of ECC into XI wherein XI can make use of the data.

Here the data from ECC will be changed so frquently that we need to update the data in XI also.

So please suggest me if we can go for Value mapping or Lookup Table in XI-Abap stack.
1. incase of Value mapping, i think we cannot update value mapping, here please suggest me how can I delete and insert the new data in the same time.

very helpful if any link has steps of this.

2. If XI-ABAP stack lookup tabel is best, will there be any issues I should take care?
