Update Existing Sales Quote to include Project/Task

Hello Everyone,

I have an import scenario and business event that create a new project from an SO Quote. There is an attribute on the project to bring in the quote number. After the project is created I have another import and business event that is supposed to insert the projectID and taskIDs back into the quote. I keep getting an error that says the ‘project task’ cannot be empty. 

Here is my most recent import mapping:

As additional info, I made the taskID = the LineNbr on the quote of the original import that creates the project. 

Anyone have an idea on why this one is erroring out?

Thanks
