It already exists, you cannot transfer or adjust into the negative. Only issues can go into the negative, even with allow negative turned on. 

Besides good practice, I believe this is because tracking the cost layers with negative transfers and adjustments would just be too complex and even if they worked, too complex of a paper trail to figure out what happened when a new receipt comes in.  

Hi @bryanb39 

Please provide details on how you accomplished this scenario at your end.

I have thoroughly investigated the issue and at present, if the 'Allow Negative' checkbox is selected, there is no other way to prevent a Transfer from being released when there is no quantity available.

To control the release of a Transfer when there is no quantity available, the ‘Allow Negative Quantity' checkbox can be unchecked in the Item Class.

@manikantad18 sorry I didn’t respond earlier. I was able recreate what you were talking about and transfer into the negative when doing it from the web.  

However when doing it from the mobile app, which is how we do most of our transfers, it does prevent you from going into the negative.  That is why I was thinking it prevents transfers.  

Is it possible to use the app for transfers?  I did not test using scan to transfer from the web, but am thinking it would have the same behavior as the app and prevent it.
