BAPI: Create batch split item for exist DN.

This BAPI  BAPI_OUTB_DELIVERY_CHANGE can create batch for split item, But only effective for more than two batch.

For example:

Item 10 ;  Material ABC

Batch:

2016032301

2016032302

When only split 900001 with batch 2016032301, this BAPI will update batch number to item 10, no 900001 line item.

If split two batch, this BAPI will create two line item ( 900001 and 900002) correctly.

Even split one batch, how to force create 900001 line item for this BAPI and don't update batch to line item 10 ????
