Workaround to use System tables in AL extensions

adas

I have a c/al object using Object table. Given, System and Virtual tables cannot be extended, how can I accommodate this when converted to AL?

You cannot add fields to the table using a table extension.
But you can use the object table in AL, just as you could in C/AL.

That depending on what you use Object for.
What kind of info are you looking for?

I have a field in a table that is referring to Object table using TableRelation (Object.ID WHERE (Type=CONST(Table)) . The solution is not compiling and error is showing in TableRelation property. Error is - 'The type or method Object cannot be used for Extension development'

It seems that we can use AllObj table instead of Object table. Some system/virtual tables are not usable for extension development. However, AllObj is allowed. this link can help.
