Create Batch through RF in EWM

Hi Gurus ,

I have a requirement where product is batch managed with SLED maintained in ECC. This product will come to EWM without batch.

Now in EWM on RF if I need to receive the products , what option can I use where the batch can be created and GR can be done.

Batch created in  EWM should be able to flow back into ECC as well. We have a option in RF but it works only with HU and with external batch number.

We need internal batch assignment like we can do from T-code /SCWM/PRDI create batch button.

Please let me know in case you need more input from my side.

Thanks,

Abhishek
