IDOC for stock transport order

Hi,

I cant locate an idoc that will create a stock transport order. Any ideas ? I can create a std sale :purchase order using ORDERS05 but cant find how to create an STO

Is there such funcitonality ? and if so whats the processing code / FM ?

In retail there is the concept of a store order where a POS system sends in a replenishment order and this can get created as a requisition / sto etc .. im trying to replicate this in an R/3 4.6C system.

thanks in advance
