Not Able to delete data from internal table to Data Base Table in table control

Dear All,

I am working on table control, i am looking to delete the data of z-table if that data is being deleted from table control. I have created a table control, in that data is coming form three tables. 2 of them are z-table and one is standard table. now what i want is, if we select a row fro table control and press delete, in that case it will delete the data from all the 3 tables. but in my case its only deleting the data from the final internal table in which i have saved the data from three database tables. So kindly suggest.

Thanks and regards

Jai
