BAPI_OUTB_DELIVERY_CHANGE - Batch Splits don't work

Has anyone been able to perform batch splits via the bapi BAPI_OUTB_DELIVERY_CHANGE? Not positive this is the correct module to use, but best I can tell it is.

My goad is to be able to determine how to update a standard Inventory Managed delivery (no WM, decentralized warehouses, or ALE systems) with multiple batch splits per line item. Need to know if this is the correct FM to call and which tables you had to populate to pass the material, batch, quantities, unit of measure.....

Any help would be greatly appreciated.

thanks,

Chip
