Hi Sasidhar Gupta,
1. Please check whether uploading stock material exist in EWM . if not CIF the material.
2. Please check the batch also whether exist in EWM .
3. Above things exist correctlly. check your CSV file any spaces exist.. for product.
In case any extra space exist also system cannot identify or validate properly.
Hope this is useful.
Thanks,
