RE: Linking two tables in Business Central using AL Language
There are many ways to do that. Depending on exactly what you want to achieve.
Using list parts and card parts is one option.
You can read more about the pages types here:
docs.microsoft.com/.../devenv-page-types-and-layouts
If you only want to display data and not have them editable you can use the integer table as you datasource and simply use AL code to pick and data you want to display on the page.
But ListPart or CardPart should normally be your 1st choice.
And just for the record. You can not link any two tables together. They need to have some kind of relation between them unless you just want to display data from a table with a single record.
