LPD_CUST application alias

Hello,

I have created a table . This table is maintained in SM30 . In this instance there is a column and a column alias.
I now want to create an F4-help fpr the application-alias. For this I would like after the instance has been select, view in F4 aliases.
It will then display only the alias of the selected instance . Is there a table that links the instance with its alias?

Regards Kerim
