Each of the Interface Codes can specify a different set of accounts to which to post the transaction element with which it is associated. In this case, we have only the minimum number of Interface Keys, one for each transaction element and two Inventory Keys. As a result, there are two possible keys for the first position, four possible keys for the second position, and one possible for the third position. The table shows the Interface Codes that will specify the accounts for the related element.

For example, the discount element only has one Interface Key but two Interface Codes since the first Interface Key could be CUST or CASH.

We only want to split the sales of inventory items into two accounts. To keep everything else the same we would enter the same AR/Cash account for the Interface Code CUST and the Interface Code CASH.

Then, on the Interface Codes CASHINVNTDEPT and CUSTINVNTDEPT, we would enter the same account for the opposing account and the cost of goods sold account. These would be the posting accounts for transactions that include inventory stock items with the Interface Key INVNT assigned to them. For the other group of stock items we would apply a different opposing account and cost of goods sold account for the Interface Codes CASHINVNT1DEPT and CUSTINVNT1DEPT. These would be the accounts all stock items with the Interface Key INVNT1 attached to them would use.
