Delivery batch split

Hi Gurus.

Please help me with the following:  the parts are managed by batchs, the items are of category D020 in the order.  How is the batch split done in the delivery, if possible? 

I face the error messages:

/DBM/DELIVERY120     Item &1: adding items to DBM order delivery not allowed

/DBM/DELIVERY122     Batch split is not allowed for DBM order-based delivery

Thanks.
