Hi Yogi
Process is create IBD in ecc >> system picks wh no and find , is it decentralised ? via customisation flag for WM, then it gose to distribution model and find program to send to ewm logical system.
if queue is in SMQ2 ecc then it issue of save replica program is not picked for wh via distribution model.
check bd64 for dist and distribution model you have created for WH and does it has programs,
