No further GRN - scenario

Hi Experts,

I want to "no GRN" for a line item in PO but invoice should be posted. I dont want to make this setting at vendor level but at PO order level.

I tried to enable "no further GR required", so it doesnt expect GRN but when I post the invoice, but Invoice is going to "waiting for preceding document" status.

Any help?

Regards,

Senthil
