How to know which ones are the internal tables of SAP DS?

[former_member410676]

Hello,

In my system, the development database schema is the same as the one used by SAP to manage its internal tables.

As I didn't made all the user tables inside, I would like to know if there is a way to differenciate the ones creates by SAP from the ones that weren't.

I'll attach the list of tables I'm not sure from who they come:

I would like to know if I delete one tables from SAP, will the tool stop working or it will generate it again?

Also, is there a pattern or prefix or anything to differenciate this tables from the others?

Thanks and regards
