I validated a Quality order and it goes to Status fail and I Try to Re-Open the Quality Order for test again but when I try to Re-open the quality order I got below error in AX 2012R3
"You cannot block 11.00 items. Only 0.00 items are available on the inventory."
But It same Process works and allow to re-open for Quarantine warehouse Item
in AX 2012R3
Where is the stock? Looks like you have used it or sold it , so the system says you cannot test them as you don't have them.
Also you then mention quarantine orders which makes the flow slightly confusing.
Moved to user forum (as you have posted it in Developer forum and i don't see any dev related requirement in the post).
