1. Reversing already allocated receiving documents
If you select the Change Sign (Reverse Document) option in the adding window, and the received quantities which you wish to reverse have already been allocated to individual orders or work orders, you must first reverse the hard allocations before you can reverse the receiving document.
The easiest way to do this is by unchecking the allocated quantities in Hard Allocations tab. In the Lines tab of the document or credit note, enter the item ID without a quantity; now go to the Hard Allocations tab. Here, you can view and uncheck (reverse) any allocations of the item.
If the allocation of quantities that have already been received is not cancelled and you try to lower the received quantity (which would lead to negative stock since a greater quantity than is currently on stock would be allocated), the porgram will not allow you to reverse the line and will return an error: Quantity is already partially or completely allocated!
2. Reduction of received quantity
The program will also return this message if you try to reduce a default quantity which has already been allocated. (See Quantity is already partially or completely allocated!)
3. Issuing allocated quantities with transfer documents
Transfer documents represent both receiving at the destination warehouse and an issue from the issuing warehouse.
If you try to transfer quantities that are already hard allocations from one warehouse to another, the program will return an error (see Quantity is already partially or completely reserved!)
