Hi Krishna,
Thanks for your answer and sorry for late reply. Actually i was trying to figure out about licence thing and finally i came to know. It's not free even for existing ECC customers but yes there is only one time cost (that also very less) for existing ECC customers. SAP team said they charge for SAP gateway interface usage. Anyways once my team will complete this process than only we guys will come to know all about it.
Krishna thanks for your detailed answer. I appreciate your help.
Thanking you,
Kind Regards,
Kapil
