Create Supplier drop-ship through Internal Sales Orders Process

 Hello,

Ex   OU1/Org1 purchases gallons of liquid from Supplier1, sells directly to end-users, as well as supplying other OU's.

OU2/Org2, sources all of this liquid form OU1/Org1, however, these are very large shipments (such as 100-gal cases)

We would like to Signal the demand from OU2/Org2, through Internal Requisition to OU1/Org1, but dropship directly form Supplier1 to OU2/Org2.

Is there any way to automate this?  Note: orther OU's also replenish from OU1/Org1, but may not need to dropship.

Thanks

Ben
