Inventory Journal

Can anyone explain what the reason is behind the inventory Journal
that you set up in the company configuration screen. I think that I
understand what the help file is telling me but I am not sure I
understand why.

My interpertation of the help file

issue materials to a job

Debit - Inventory Journal Number
Credit - Inventory Account

then

Debit - Wip
Credit - Inventory Journal Number

is that right. If so can someone explain the reason for this.

Thanks
Rhonda
