Cannot select project task in a new customer invoice

Hello @Rmak0501 ,

I need to answer your question with more questions - I hope the questions lead to your answer.

1. If you click Tools → Trace, is there any error or information recorded that may help us know what happened?
2. Is the Task ID disappearing for just one new project?  Does the Project Task ID work fine now for other customers, other projects? 
3. Is the site customized?  If Yes, does the Invoice line have the same behavior when customizations are temporarily un-published?
4. Do other users (such as administrator) have the same problem when entering an invoice to the same project and task?

Thank you.

Hi Laura,

Below are my answer.

1. I find one exceptions but have no clue what that mean.

   

2. The project task just disappear for this project
3. The site is not customized. We don’t have any customization at all :(
4. My colleague also get the same problem.

Thanks!

Hello,

Please open two projects screens side-by-side and compare field by field:  one project that works, compared to the “problem” project. 

Does any difference stand out? Also, what is your version?  

Thank you.

Hi Laura,

I make changes in the project that have problem. The problem still exist (i.e. the project task disappear after I pick it). But I find a red cross mark which said “Object reference not set to an instance of an object”. Any idea what that mean?

Thanks!

Hello Raymond,

The message above, “Object reference not set to an instance of an object,” can indicate an error in a customization.

Please check again the Customization Project screen in ALL Tenants on your site, and look for published projects.  It is possible that published Customizations appear in Customization Project screen for only one tenant, when they have been published to every tenant.

Hi Laura,

The error message seem to appear after I remove the item in the column “Inventory ID”. It doesn’t show again after I enter an item in the column. However, I still have problem to select the Project Task.

@Rmak0501 this might be too easy but is the project task active?
