Reproducing the Issue

  1.  Go to Project management work center
  2.  Go to Not invoiced time and expenses view
  3.  Enter and search for respective Project
  4.  Select it and click on edit time and expenses button

You will see that negative quantity is appearing.


This means that after a project invoice request is created you have canceled the respective time confirmation or changed the project task on the respective time confirmation


1.Since you did changes to the time confirmation you are suppose to either

A.Cancel the Project invoice request(before this cancel customer invoice as well if any), and then the negative quantity will be removed from Not invoiced  time and expenses.

B.Else If there are many more time confirmations to be done in future then

Wait for a new time confirmation to be created with little higher quantity compared to negative amount and then when you create new project invoice request that has details of both negative and newly created time confirmation with positive quantity, the quantity will be subtracted and only remaining positive quantity will be invoiced . Which ensures that you do not over charge customer.

Also you may contact your partner to help throw an error or warning, if you change or remove the time confirmation for which already Project invoice is created.
