Could not find the item to pack using RF when creating new hu

Hi All ,

I am currently working with an additional product found during inbound process .

I receive an new product in EWM , not sure how to handle it in RF .

Yes there is development needed if a new product has arrived in the warehouse .

I can use the GRPE transaction to do the further process but I am looking for RF .

We have a standard process when using RF inbound--> unloading --> Unloading by delivery -->Press Create new HU .

This works fine but when ever iam giving the packing material the system is giving error .

" could not find the item to pack "

I have attached the screen for reference .

Please help what can be the reason for this .

Thanks
