DELVIERY IS NOT HAPPENING TO THE EXTENT OF ORDER QUANTITY

Dear All

I have Sales order with 10000 KGs as order quantity, now iam doing partial deliveries against this SO once i deliver 7 to 8000 Kgs further system is not allowing me to do delivery System Messg "No delivery-relevant items in order 0030048212, order type ZVCS"

though Sales order stock is present in MMBE.

Once i increase the order quantity i am able to do delivery

My observations Overall status Completed in SOrder Status, Delivery status Fully delivered and in the Sales order overview screen Delivery block filed is in display mode

I have checked all the possible settings but i could not find any solution, even i checked with my technical consultant even then i could conclude.

Kindly share your views

Regards

BMS
