AIMZ shows invoices as soon as they are received or in workflow in the accounting system, not only when they are posted. That is why you can see unprocessed invoices on the contract before they are fully approved. You are welcome to process them in advance.
How to do it
Open the contract in Purchasing and select the Invoice tab. The Invoice Link column shows what each invoice is linked to.
Link the invoice as usual, for example to the contract or a production code.
If you are unsure about the coding, wait until the invoice is posted. It is then in the blue status box Unlinked under Invoice → Incoming Invoice.
Good to know
Processing in advance means less backlog and a better overview along the way.
An invoice in workflow can still be recoded in the accounting system.
If the production code is changed later in the accounting system, the invoice is marked with a blue information icon in the Production Code column because it differs from your choice. Check it and correct the link if necessary.
