Invoice Number formatting glitch Dynamics NAV

Posted on by Micheleish 105
Client states that although numbers are auto assigned, sometimes anomalies occur with the posted sales invoice numbers.  The invoice is usually in a certain number series 6 digits.  It is set up for no manual numbers allowed.  In fact the user cannot even see that field when creating a sales invoice or posting a sales order.  Does anyone know what could be the cause of such a glitch?  Thank you,

    How do you create posted sales invoices, from a sales order or from a sales invoice? Subsequently, what number series do you have setup in the Sales & Receivables setup for sales invoices and posted sales invoices? Perhaps if you create a posted invoice from a sales order as opposed to a sales invoice the posted number will be different.

    It looks like someone selected a different No. Series. If it wasn't changed on the document, is it possible that the value in the Sales & Receivables setup was changed? And then changed back? Another possibility is through external system integration, or the developer inserts it from the code themselves.
    PS: 
    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?)
    Dynamics 365 Business Central: Empty Posted Sales Invoice with only one comment “Document created to avoid gap in No. Series”? Why?
     
     
    Hope this can give you some hints as well.
    Thanks.
