I was trying to add working address and home address for employee but it couldn't be created without adding account payable and account receivable on accounting tab of working/home address creation (why there even is accounting tab on working/home address?). Why is this information needed for working and home address?

At this moment only way to add addresses for employees without including this data was to remove accounting modules which works fine now when we aren't yet using OpenERP for accounting but won't help in future so we need to understand why this is needed.
