Hi,
I see a behavior in standard Contoso environment USSI that I can't reproduce in other companies.
In the project management module, I choose a project of a type time and materials. When going to create an expense journal against this project the category automatically defaults in. Also, the offset account for the journal defaults it. How is this achieved?

When I click in lines, this appear with the fields you can see appearing by default.

I am using T&M project to accrue expenses that will be recharged later on. So the posting I'm trying to achieve with the expense journal is to debit accrued income (this part is ok) and to credit the expense account where the expense was initially booked. I would like to create project categories for each type of expense and link them to main accounts so they will default in as offset account in project expense journals.
Any idea of how this can be achieved?
