Avoid copy of 0 quantity items from billing doc to credit memo request

Dear colleagues,

I want to create credit memo request (sales document type CR) with reference on billing document. When I do this I get items with 0 quantity in CR document. Reason for this is that I use batches, so when I sell some product sell different batches, so I have sub item lines in sales order, and delivery.

for example:

when I create billing document I get billing items like:

which is not a problem.

Problem is when I try to create credit memo request with reference on billing document, all item lines with 0 quantity (like item 10) are copied, and making me problem because CR document does not allow items with 0 quantity and I need to delete them all manually. which can be real PITA if lot of these items exists

Could you please help me how to avoid this 0 quantity items.

Thank you,

Harry
