Hi @bclark  I have imported this GI in my local instance and I don’t see any issues with it. I’m assuming that this issue is related to data but not with the GI.

Have you checked this GI in any other instance?

@Naveen Boga 

I just checked in my test instance and it worked as expected. So thank you for helping make the determination that it is not anything wrong with the GI. 

Do you have any advice on how to find where the issue in the data is then? 

@bclark  Have you attempted to uncheck fields from the Results Grid one by one and verified the results? If not, please proceed with this step as it will assist us in identifying the root cause of the issue.

@Naveen Boga 
I went through the fields one by one and finally discovered that it was the Customer.PrimaryContactID that was causing the issue. 

One specific customer made an order yesterday. I still need to figure out what’s wrong with that field, but I excluded that order number from the GI for now and it works again, so thank you!

@bclark Glad that you figured out the issue and sharing the update!
