I am bit confused now. I thought you had a delivery to a sales order and you got negative quants (in 916 storage type) after you posted goods issue.
But now I see storage type 100, is that an interim storage type or does it have the real physical quantities? Physical bins should not be allowed to go negative.
You have to move the quantity from the positive quant to those negative quants to make them going away.
It is probably caused by the fact that you had the same material 4 times in one delivery and no stock in the bin. It is probably not possible for SAP to total this into 1 negative quant if this happens under such conditions. You may need to retest this case to be sure. If you can get the same result then contact SAP, maybe you have luck and can convince them about a program bug.
