The inventory it’s showing negative numbers, I already checked the purchase invoice and all the ítems are correctly uploaded. I have 6 months working with this program and it’s the first time this happend. Saturday was all good but today none of the purchased items are in the inventory.
Please show the edit screen of the PI.
this is not the edit screen. Also please show in full.
This is an example of one item that I already upload the purchase invoice but today the purchase invoice it’s not showing the items in the inventory
That is the view screen, please show the complete Purchase Invoice Edit screen.
Ok, I’ll get the screen shot
Also a screenshot of the editscreen of one of the Inventory items. Please show the complete screen!
I choose the item code 320-533AZ-MV for the example, but the problem is in all the purchase invoice. I never had this problem until today
As you can see, only the write-off is showing in the items, but no the purchase invoice
Did any of the screenshots helped?
I already figured out. For anyone having my problem, now you have to go to every purchase invoice edit and select the option Also Acts As Goods Receipt, and items will appear again on Inventory Items. Thanks for the double work Manager IO 
See for explanation:
You could use Batch Recode or Batch Update for that.
