Display work center layout with T-type Packing in Inbound Delivery

Hi,

I have just created a work center and specified the transaction type is 6-Packing in Inbound Delivery. I was trying to check how to print the HU label in inbound delivery after packing.

The funny thing is, when I was creating it, the system does not allow me to save due to the warehouse number is not within the name space (don't know why) when I choose transaction type 6-Packing in Inbound Delivery.

My workaround was that to copy an existing one with T-type 1-Packing General and then change the T-type. It worked.

But after re-entering the maintenance screen for the work center layout, I couldn't see the one I have just created. I tried to do it again but the system threw a message, saying that the key already existed.

I don't know why this work center is hidden. the EWM version is embedded EWM on S/4H 1610
