Hi!

You have to clean up the records from the second table for yourself.

DELETE FROM second_table WHERE foreign_key = first_table-key.

Thanks for the reply.

But I have multiple records to be deleted from first table. So I have to loop to delete records from secondary table. Can I do without loop.

Of course you can.

1. You surely have an internal table, with the entries to be deleted. This table must have the primary keys of your DDIC second_table.

Then use the following code :

IF NOT itab[] IS INITIAL. "don't start the deletion using an empty table

DELETE second_table FROM TABLE itab.

ENDIF.

2. Or you can use the DELETE within a loop.

For more details on the DELETE command, simply press F1, on it, within the ABAP editor.
