Updating item in warehouse quantity available for shipment will go negative

Hi ​@MarkD 

Try checking your "Inventory Balance" to see if that item, by Location & Lot/Serial, has enough "Available" items to make a "Purchase Return".

Hi ​@nhatnghetinh - there is stock on hand but 0 available.

Hi ​@MarkD 

There is stock on hand but 0 available => Please check the following reports to find out why available = 0.

Hi ​@nhatnghetinh - Inventory Allocation details was sent prior to your response. Below is a screenshot of Inventory Transaction history. I’ve checked all these reports already and they don’t make sense. Item hasn’t been issued out yet based on those reports. I don’t know if it helps you provide me an answer, but the Purchase Receipt that I was trying to return has a ‘Goods for MFG’ line type.

Hello ​@MarkD ,
