Open delivery for goods receipt via RF

Question

I am trying to do a good recepit through the RF menu. Once I click on the goods receipt , it takes me to the screen which asks for PO/delivery #, Material # and quantity.
When I enter in the PO, mat # and Qty , it gives me the error message "No Open Delivery"
So I went through the RF screen overview documentation which also says that "Material must exist in the order and in the open delivery"
Can anyone please explain what this means and how can I create an open delivery?
Thanks

1) you need to create custom RF Tcode where you can design a screen to enter the batch and update it.
2) Serial number is at IM level, if you want to trace it at the WM level then you need to go for custom program.( In standard it is not possible to track serial number at bin level)
3) try doing research on LM71, LM72, LM73, LM74. LM76.
4) There is not standard RF tcode to create TO, you need develop a custom Tcode.
    You need to sit with business to design the screens of this Tcode( mandatory field would be material, source storage, bin, destination storage, bin, SUT, )
   you can call function module L_TO_CREATE_SINGLE)
