AP doesn't autonumber invoices.

Do you have a suggestion as to what might be happening?

The invoice number already exists.  Change it.

"The invoice number already exists.  Change it." - I know that.

Do you know or care to suggest as to why this situation may be happening?

Somebody manually entered it already.

Maybe an overview of the scenario is in order.

Client enters Receipts (against vendor invoice num 123) in IC. No PO module. After posting and Day End the client goes to AP to raise an invoice against Document Number 123 and on tabing out is hit with the error - "Invalid input.  An invoice with this number already exists for this vendor. If you want to add this invoice, add characters to the invoice number to make it unique."

So in AP the user (client) wants to track the document against which the receipt was made so that the AP Clearing account clears and Inventory is debited and the Customer account is credited.

In the AP invoice entry screen, the Document Number field is mandatory - what is this referring to in the IC receipt screen?

Any thoughts will be appreciated

IT ALREADY EXISTS!  SOMEBODY ENTERED IT TWICE!

CALM DOWN! YOU DONT HAVE TO REPLY YOU KNOW - THIS FORUM CAN EXIST WITHOUT YOU!

Here's my two cents worth.  

The only way that an AP invoice already exists is if a data entry person entered that invoice number for that same vendor previously.  The system does not pre-number or otherwise assign numbers to vendor invoices, right?  It is a manual entry by the operator and the system always checks to make sure that for the same vendor, the invoice number has not already been used.  If it has been used, then you get the error.  

That is what Jay is trying to tell you and what you need to do is to check that vendor's history to find where and when that initial document was posted and by whom.  

Then do what the program is prompting you to do - add a suffix to the number so that you can enter you AP invoice.
