GR Cancellation not allowed despite sufficient stock balance
We are trying to cancel a GR for an item with a total quantity of 5 cases. However, system prompts the message "Deficit of SL Unrestr. prev 4 CS".
We checked the stock balance of the item thru MB03 and MMBE and the reflected unrestricted stock is 20 cases. So this means, we have sufficient stock balance to accommodate the GR reversal.
Why the error? Please help.
