Post Goods Receipt in SAP EWM without inbound delivery from ECC
I have a query regarding goods receipt in SAP EWM. As per my understanding to do any kind of goods receipt in EWM, we need a corresponding inbound delivery replicated from ECC -> EWM. Is there any way to post Goods Receipt in SAP EWM directly without corresponding inbound delivery origination from ECC system. Physical Inventory is one option but involves too many steps and I am looking for some simpler options which can be automated in background.
My business requirement is assets are scanned via RF in EWM system. In current process if any asset fails(due to absence of corresponding inbound delivery) then one custom program is run in ECC system to create inbound delivery -> replication to EWM -> final putaway. What I want to know is - is there any way to post goods receipt directly in EWM and then transfer to ECC to create transfer posting in ERP system.
Awaiting for responses!
