Serial numbers for materials

hello,

I have done a setup for serial numbers and when I do the GR I get a blank serial number list.

I earlier used transaction IQ04 and maintained for one article the various serial numbers.

When I do the GR I must be able to autmaticlaly see all the serial numbers related to the article. The system shows blank serial numbers although I have maintained them.

Can you help to identify what I have missed that the serial number based on aarticle doesnt get coped over to the GR document?

Another point is when I do the GI I also dont see the serial numbers for which I have done the GR for the article. What am I missing here?

Thanks
