Table Control Help required

[arvind_soni]

Hi,

Right now I am working in table control.

I have an internal table that is getting displayed onto the table control,the internal table has the primary key MATNR in it.

When the user enters an identical MATNR in the second row the validation should throw a message that'Entry already exists' and the entry should get deleted.

The internal table is filled up from the database table using the WBS Element.Then before saving the new entry ,the database entry for the WBS element is deleted.

After updating the Internal table the internal table is inserted into the database table.

Can anyone let me know how to validate the new entry against the entries already existing in the internal table.

Hope i am able to make the problem clear to you.
