Redetermine Batches in Outbound delivery

Hi,

We have following situation

Material maintained in batches

Stock available is : Batch XXXX 1000 qty

PO raised with Qty : 1100

Outbound delivery : 1100

Line Item 1 --- Qty 100 No Batch

Line Item 2 --- Qty 1000 Batch XXXX

So as stock is less than 100, we can not do PGI.

After 2 days we receive material and now we have Batch YYYY : 100 Qty

So now can we redetermine the new batch in existing outbound delivery so that we can PGI ?

Can it be done by config or we will have to enter this batch manually in Line Item 1, everytime it happens.

Please guide.

Regards
