PI integration with BI/BW using Datamart

Hi Experts,

We have one new requirement to integrate BW system to PI using data mart.

They want to go for the approach mentioned in this thread: https://help.sap.com/saphelp_nw73/helpdata/en/4a/495746ea8b1c46e10000000a42189c/content.htm?frameset=/en/4a/547e806a8a1cd4e10000000a421937/frameset.htm&current_toc=/en/a3/fe1140d72dc442e10000000a1550b0/plain.htm&node_id=362&show_children=false

If anyone has worked on this approach please provide your suggestion.

Cheers,

Vikram
