Hi.

Your available quantity is 0, that is why you cannot issue anything.

@Arend ,

We have a purchase order for the specified activity . However , the quantity is not available to issue . Will that be assigned to another activity ? If so , how can I find it ? 

It was scrapped, so no you don’t have it available to use and it isn’t assigned to another activity.  It is scrapped.

@Arend and @ShawnBerk  Thanks a lot . The specified quantity issued to incorrect activity and corrected now. Thanks for your corporation
