We used "Object Metadata" in the past, reading table relations from its BLOB-ed XML specification, but access to that table is blocked for cloud development and due to that we have access only to "Table Relations Metadata" table, which gives only partial information about table relations.

This is an issue when working with both Public Cloud (SaaS) version of Dynamics 365 Business Central and with On-Premises installations.

Therefore please, consider adding missing information to "Table Relations Metadata" or another metadata table or unlocking "Object Metadata" to be able to get full information regarding the missing information and table filters.
