Why system read different PO number for invoice posting?
Invoices have different legal identifiers relating to the original purchase order - this is common to allow part invoicing against part delivery. It should create no issues.
But when i look into the table VendInvoiceJour there is no record for the particular purchase order id. Same goes to VendInvoiceTrans table.
I was trying to post invoice for a purchase order. But unable to post. When i look into the invoice history form, there are many ‘pending’ records exist. Is this can cause problem for the invoice posting?

Not only that i tried to delete in the vendor invoices> pending vendor invoices too. And I face the same error message.

Ohhh…really?? I don’t know that 
yerp…i did…
I dont see any pending invoices now in the forms. but i still unable to post the invoice. I have no idea how to solve this problem…
Well now you have deleted data through the back door and probably left relational tables populated you are stuffed. You need to get someone like your partner to come in and resolve the issue now.
Alright Adam…i will…thanks for the advice…
