Sage 100 Customizer DMAIN and DMAINW

SOLVED

When I use Sage 100 Customizer to add customized panel, I noticed each panel has a W version, eg, In the task of Sales Order Entry,  there's a DMAIN and a DMIANW. What's the difference between the two? Can I set the default display to be DMAIN instead of DMIANW?

Thanks.
