How to Access Metadata Publisher

Hello! I am a consultant working with a Movex/Lawson client who is requesting that I build some custom applications for them based off of their Movex/Lawson tables.

The trouble is they do not know where the data resides on the database, they just know which Lawson screens they use to enter the data.

I have been researching and found that Lawson's Metadata Publisher (MDP) might provide me with the information that I need. I have access to the MyLawson portal, but when I try to access the MDP from the "Support" dropdown is just tells me that they hosted version requires a license.

Am I somehow accessing the MDP incorrectly? Where might I find this information? Specifically, I am looking to find the "Remarks" value on the PPS 300E screen and the Requested Delivery Date and "Ship to" on the MMS100/F screen.

Can anyone be of assistance?
