At the moment it is mandatory to define all table types inside a solution (except for supplemental). So in addition to the master definition, you would have to specify a document and the ledgerEntry as it is done in the demo. I understand that you might not need the other two. I am working on making these other two optional so that your example will work. This improvement is planned for the next release.

This problem is already tracked in #14. So I am closing this issue.

This issue was fixed in version 0.4.0 of the mdAL VS Code Extension. Please update your installation and the example you provided should work.
