Separate chart of account for each point of sale. And show separate line in Profit & Loss report.
1. I created 3 point of sales in `pos.config` model.
2. Created 3 Journal for each Point of sale.
3. Created 3 Chart of account with type `income` and assigned to each Journals.
When i make a sales through one of these POS, the sales amount should be accumulated to corresponding chart of account instead of default chart of account '401100 Sales Account'.
