How I could get the value of some SM30 field to filter in a search help?

Hi,

First thank all of you for your time.

I have need something that I'm not sure if it's possible.

I have done a search help and I need to delete some entries of the table that I show to the user to select one value, when they presh on the matchcode.

In the search help I could delete some entries of this table but I would need the value of another field of the SM30 to filter.

Is there any way to have this value on the EXIT FUNCTION of the search help?

Best regards.
