Hi Jaagrit,
Are the Goods Receipt items appearing in the work-list for Import into CWH? And, if so, are you able to create the Import Declarations ok?
If you can create Imports into CWH, then please check the "Admin." tab in the Declaration Item and confirm the Destination Procedure - is it showing "Customs Warehouse"? If so, then what do you see in the "Receipts & Issues" list for the related Product(s)?
Regards,
Dave
