batch split line in delivery

Hi,

In my system, I have configured automatic batch determination for my delivery item category.

Now when the system determines the batch, even if there is one batch, the system creates a batch split line (with line number as 900001).

Is this a standard system behaviour?

Is there a way that we can have only one line if there is just one batch and go to a batch split line only when there are more than 1 batches.

pls let me know. Any help would be highly appreciated.

Thanks

AB
