E.g. suppose I have an office rent of 6000 per month, but I have to pay 3 months in advance, one month deposit and one month agency fee. Let's say 1/january I rent the office and I assume I rent it for 1 year.

I assume I should do something like this:

1. Create an an accounting entry in the miscellaneous journal with:
   1. Add 3 lines for the rent, 6000 each to account office rent, each line has a different period: january,february,march
   2. Add 1 line for the deposit to account receivable for december with 6000.
   3. Add 12 lines for agency fee, 500 each month, each line has a different month, account to office rent.
   4. Add 1 line to account payable, total 5x6000 = 30000.
2. Then we transfer 30000 by bank, add the bankstatement and reconcile it with the accounting entry in account payable.
3. Then every 3 months, just add a new accounting entry with only 3 lines for the rent (e.g. april,may,june) and 1 line for account payable of 3x6000.
4. The moment we receive the deposit back in december, we enter the bankstatement and reconcile it with the accounting entry in account receivable.

I am not quite sure this is correct, both from accounting principles and from openerp principles.

I am running in the following trouble:

1. When entering an accounting entry, I can only select one period (I have setup monthly periods). I can select different due dates though. How to do this?
2. When trying to reconcile the bank statement, it gives an error, integrity error object with reference: account_id - account.id.
   I think it's because I didn't select a partner? So should create a partner called office owner and assign each line to this partner? Or is it common to make one partner called "Other" which I use for all office costs (equipment, consumables, rent, couriers etc.) Creating a partner for each seems quite an overhead, especially for small costs.
3. Another way I could do this, is by letting the office manager adding an employee expense. She actually does pay it and then I give it back to her. But then I have no idea how to account over multiple periods.
4. Another way I could do this, is by adding a purchase invoice. But that doesn't seem quite right to me, as I use purchase invoices for a suppliers that deliver goods that I actually sell.

Any help on this, greatly appreciated!
