Scrapping Process in Bonded Warehouse

Hi Experts

I have both duty paid and duty unpaid stocks in GTS Environment.

In ECC, we used MB1B with movement type 311 for scrapping. After doing the same, the Material Document Number is getting updating in work list of " Process Scrapping Operations " under Custom Warehouse tab in GTS.

When we select the check box and click on Process Entries button, a pop up appears and it asks for New and old values.  We are not able to process the entries as system again and again asks for new and old entries.

Not sure whether we are missing any step.

Can you please help on the same.

Thanks
