MDM5.5 Matreial master lookup table: Lisitng and delete Maps

Hi

I generated the XML file from ZMDME_EXTRACT_MATERIALS_553, and start Import Manager with the xml generated.

1. When I try to Open Map with File->Open, I see nothing, what has been missing? I have done this before but somehow not working now.

2. How can I delete the list of saved map in Import Manager?
