no. series code in posting purchase invoice

Hi

I could not proceed posting the purchase invoice since it is asking for the no. series code. There is already a no. series code set up for this invoice.

Can someone pls. help me on this. I am using NAV 5.

Thanks

Gella

It’s not an error - you must set up No series for POSTED PO/PI. Posted docs have separate No series.
