Replenishing stock from WH to WH

Hi

I have taken a look at Replenishment control which seems to be replenishing stock within the same WH using the Picking storage indicator to derive which storage type to pick the stock from.

My question is what process in SAP supports replenishing inventory between two WH's?

Eg)

Sloc1 linked to WH1.

Sloc2 linked to WH2.

Stock in WH2 needs to be replenished from WH1.

Many thanks
