Error while creating in billing document

Dear Pals,

I am doing Intra-company stock transfer and have created sto and outbound delivery (vl10b) and picking also. I have pressed post goods issue button for goods issue in VL02N and tried to create billing document in VF01. But it is throwing an error

"Delivery Type NL cannot be invoiced with billing type F2"

Will it be enough if we press post goods issue button for goods issue..??

Kindly resolve this.

Regards,

Prasath
