Interface Rules

The general ledger dissections are broken up based upon a set of Interface Rules that are applied to a transaction type.
The Interface rules are pre-set and usually not touched.
The only real-time you would change interface rules is if you have chosen to break up the standard Readysell chart of accounts to be by Department (what we call Product Category).
If this is the case, you need to ensure you have a chart of account to stand for each product category required, a product category set up, the general account then needs to be assigned to the correct product category account and the product category assigned to the product itself.
Then you can make changes to the Interface rule if you wish to dissect against the Product Category etc.

If there is a product that is in a Product Category that you don't want to apply this interface rules to, you will need to create a new product category and apply this product category to the product.

Please also note, on Non Stock Products the costing method for each Product Category needs to be set up correctly.

Please note:  If you create sub-department chart of accounts, that is you have decided later on to break up Sales Revenue by Department being Sales Revenue Stationery, Sales Revenue Furniture etc, you need to speak to Readysell.
Creating a sub-department chart of accounts after you have been using the standard chart of accounts does not mean that all previous general ledger postings will be moved to the newly created general ledger account for that department.
