I have written a formula column in a matrix report. I want to display a zero instead of a blank field where there are not recordd. When I run the report I get the error REP-2103: Column 'Zero_disp' PL/SQL formula returned invalid or no value. How do I trap this error. I have tried the no_data_found and SRW.DO_SQL_FAILURE and others. All these failed. Any Ideas.
