Regd Inventory

Hi Experts!

In FI extraction How to do stock initialization in BI,

I 've generated DS @R3 side,then what is the procedure to load initial stock into cube?

I 've generated another DS BF/UM, for these DS do we 've need any DSO, if we need what is the suitable DSO for these later DS?

I' ve got some docs but that are related to BW,

Can anyone pls tell me hw to work on these?
