Hello there, userinfo18.

I completely understand how important it is to keep accurate records of your products. This helps you keep track of your inventory items with ease. 

It seems that there might have been an issue when converting the purchase order to a bill since the quantities didn't update. I'd like to help you resolve this issue by gathering more information.  

Could you please let me know if you convert the purchase order to a bill? If yes, did you run into any errors or issues? This will assist me in identifying if there's an ongoing investigation that needs our attention. 

I'll be on the look out for your response. Thank you in advance, userinfo18. Have a good one.
