Hi Malay,
Check your configurations for inspection document creation-at which point of time you have set up inspection document to be created i.e. at the time of GR or at the time of Warehouse Request/Inbound Delivery?
Also try to change setting for batch creation automatically in EWM at the time of Inbound Delivery instead of entering manually the batch number. Then try to run 2nd scenario again, let us know what happens.
Regards
