I'm trying to create Relations to fields in other tables from the standard BC install. But from what I'm seeeing, on the table list, what shows is the table caption, where can I find the full list of specs on the built-in tables?

    Hello,

    There is a virtual table called Field that shows you at least DataType, and a bit more information about each field. I have copied a sample page which just shows fields from the table. However the table does not know if any relatoinships have been set either conditionally (for example "No." on a Sales Line which relates to different tables, depending on Type), and it also does not know of any relations done by code. But datatype is pretty static. I hope you can use this.

    Page:

    page 50105 FieldList

    {

       PageType = List;

       ApplicationArea = All;

       UsageCategory = Lists;

       SourceTable = Field;

       layout

       {

           area(Content)

           {

               repeater(GroupName)

               {

                   field(TableNo; rec.TableNo) { }

                   field(TableName; rec.TableName) { }

                   field(FieldNo; rec."No.") { }

                   field(FieldName; rec.FieldName) { }

                   field(Obsolete; rec.ObsoleteState) { }

                   field(Type; rec.Type) { }

                   field(TypeName; rec."Type Name") { }

                   field(SQLDatatype; rec.SQLDataType) { }

                   field(TableRelation; rec.RelationTableNo) { }

                   field(MyField; rec.RelationFieldNo) { }

               }

           }

       }

    }

    This was a page, you need to implement using the development environment in BC. Or maybe there are tools for SQL Server, providing that you are on-prem?

    Yes, I have an installation OnPrem with dev services enabled. Sorry to ask simple questions, but I'm just just tryna get my footing with BC dev :)
