Sales invoice ###### already exists

Hi all,
 
I got a really frustration error in Business Central when I try to post a Sales Invoice.
 
/Sales Invoice ######  already exists./ I am totally 100% sure that this invoice does not exists within /Posted sales orders/ and the error message seems strange to me. 
 
Does someone have a solution for this problem?

Thanks,
 
Tobias

    Hi
    Please check in Sales header table, "Posting No" Field
    If it has some value then remove it and then try to post it.
    Best regards

    OK. I went to Sales header table, with ctrl+Alt+F1, and yes it has a value there. But the field is grey / I cannot change it? How do I do that? 

    Thanks,

    Do you also now my this occur? Feels like somewhat a bug, because we did nothing unusual when we tried to post the invoice?

    You cannot change this field. Your best, non-programmable, solution is to delete the sales order and re-create. If you have already shipped, you can unship and then delete and re-create. Your partner can update this programmatically.

    Hi, hope the following can give you some hints as well.
    Dynamics 365 Business Central: Manual number for Posted Sales invoice and Posted Purchase invoice (Use the same number in Sales Order and Posted Sales Invoice?)

    Please check the customer ledger entry table. Search using the document number which is shown in the error. It is possible the same document number was used in General journals for posting an Invoice
