Filling datarows before creating a new record frm-40735 ora-01422

Question

Hello
I want to create a user-control table where I Store in the Mastertable the user informations. in the 2 detail tables I store the programmnames of the first level, in the second table I store the name of the form and if the user is allowed to insert, amend or delete.
I use a Master/2 Detail-Form. When I create a new record in the master block, I want to fill in the first and second detail block, informations of another user of the 2 detail tables. therefore I created a when-new-block-instance trigger with the following code:
select programm
into :k_zugriff.Programm
from k_zugriff, K_benutzer
where r_benutzer_zaehler=k_benutzer.zaehler
and oracle_user='ROBERT';
because this sql serves more than one row I receive the error code frm-40735 ora-01422
so how could I solve the problem to insert 5-10 rows in :k_zugriff.Programm. I can not make an insert before I go to the block k_zugriff, because the user number is not commited known. Also I want to commit the form when all informations are filled in. in case of a mistake I want to exit the form with no commit;
has anyone a usefull Idea?
regards
robert
