Before posting the transaction, verify the status of Collectible in Invoice Details section. During auto invoice validation, the Collectible field is automatically marked as Y if the same combination of a service and work order status matches with the state specific rule defined in Setup > Administration > System > Vendors > Invoice Rules tab.

If the Collectible field is Y then the transaction is posted as Expense onto the account based on the setup. Else, if the Collectible field is N accounting for the same needs to be manually handled.

On clicking Post Txns button in invoice screen, the following transactions are initiated:

1. Sale of Asset transaction - indicates the amount received after selling the asset. Also while posting this transaction, system calculates the Spread based on matching spread in Spread Matrix or from Contract Spread.

All the transactions posed on the account are recorded and listed in the Collections > Customer Service > Transaction History > Transactions tab.
