issue related to IOT and ISO

 Hi,

I have setup shipping network between two inventory organizations A and B

shipping network between A to B enabled Internal Sales Order Required flag, so the transfer of stock from A to B happens with internal requisition tInternal Sales Order

Shipping network between B to A with out selection of Internal Sales Order Required flag, so we do transfer using Internal Organization Transfer.

But our issue is it also allowing transfer from B to A with Internal Requisition / Internal Sales Order, we want to transfer only with Internal Organization Transfer.

We have to go live with this setup from 10th Dec 2012, we have around 85 inventory organizations which we need to do setup, please advice.
